The upper cutoff frequency fy for the amplifier is 12.50 MHz.

Capacitance of each junction = (1/250)p

Capacitance at emitter resistance = C1 = 1p

The upper cutoff frequency of the amplifier is given by the following formula:

fmax = 1/2πRoutC

where,

Rout = output resistance = emitter resistance = R1 = R2 = R3 = ... = Rn

fmax = Upper cutoff frequency

C = junction capacitance

The capacitance at the emitter resistance is in series with the junction capacitance to give a new capacitance.

So the equivalent capacitance = Ceq is given by:

Ceq = C1 + C

The equivalent capacitance is in parallel with all the junction capacitances.

Hence the equivalent capacitance of all the junctions and emitter resistance is given by the following formula:

Ceq = 1/(1/250 n + 1/1)

      = (1/250 × 10⁹ + 1) n

      = 0.996n

Now we can calculate the upper cutoff frequency using the formula:

fmax = 1/2πRoutCeq

Rout = R1||R2||R3||...||Rn= R/n

i.e.,Rout = R/n = R1/n = R2/n = R3/n = ... = Rn/n

where,R = 2kΩ (given)

Therefore, the upper cutoff frequency is given by the formula:

fmax = 1/2πRoutCeq = 1/2π(R/n)(0.996 n)

       = 1/2πR(0.996/n)

       = (0.996/2πn) × 10⁶

       = 0.996/2π × 10⁶/4

      = 12.50 MHz

Hence, the upper cutoff frequency fy for the amplifier is 12.50 MHz.

To numerically calculate y(t) for the given system X(t) = 31(2)t h(t) = e-fu(t) using Matlab, we can define the time vector, x(t) function, h(t) function, and then convolve x(t) and h(t) to obtain y(t). By plotting x(t), h(t), and y(t), we can visualize the results and compare them with the expected values.

In Matlab, we can define the time vector t using the desired time range and time step. For example, if we want to calculate y(t) from t = 0 to t = 5 with a time step of 0.1, we can define t as follows: t = 0:0.1:5.

Next, we define the x(t) and h(t) functions. For the given system, x(t) is a linear function with a coefficient of 31(2)t, and h(t) is an exponential function with a decay factor f. We can define x(t) and h(t) as follows:

x = 31*(2)*t; % x(t) function

h = exp(-f.*t).*heaviside(t); % h(t) function

To calculate y(t), we can use the convolution operation in Matlab. Convolution represents the integral of the product of x(t) and h(t) as t varies. We can calculate y(t) using the conv function:

y = conv(x, h)*0.1; % Numerical convolution of x(t) and h(t) with a time step of 0.1

The factor of 0.1 in the above line is the time step used in the t vector. It is necessary to scale the result appropriately.

Finally, we can plot x(t), h(t), and y(t) using the plot function in Matlab:

figure;

plot(t, x);

xlabel('t');

ylabel('x(t)');

plot(t, y(1:length(t)));

xlabel('t');

If the voltage across a capacitor is a constant DC voltage (vc(t) = V), then the energy stored in the capacitor will also be a constant value, given by Wc = (1/2)Cv^2.

In this case, since vc(t) is a constant, we can substitute V for vc(t) in the formula for the energy stored in a capacitor. So, Wc = (1/2)CV^2, where C represents the capacitance of the capacitor.

Let's assume the capacitance of the capacitor is 10 microfarads (C = 10 μF) and the applied DC voltage is 12 volts (V = 12V). We can calculate the energy stored using the formula:

Wc = (1/2) × 10 μF × (12V)^2

  = (1/2) × 10 × 10^(-6) F × 144 V^2

  = 7.2 × 10^(-4) Joules

When a capacitor is subjected to a constant DC voltage, the energy stored in the capacitor remains constant. In the example above, with a capacitance of 10 μF and a voltage of 12V, the energy stored in the capacitor is calculated to be 7.2 × 10^(-4) Joules.

The discharge flow rate through the venturi meter is calculated to be X L/min, and the upstream velocity is determined to be Y m/s.

To calculate the discharge flow rate, we can use the formula:

Q = C * A * sqrt(2 * g * h)

Where:

Q is the flow rate in m³/s

C is the venturi coefficient

A is the cross-sectional area at the throat of the venturi meter

g is the acceleration due to gravity (9.81 m/s²)

h is the differential height of the mercury manometer reading in meters

First, we need to convert the given measurements to SI units. The diameter of the venturi meter is 15 cm, so the radius is 0.075 m. The throat diameter is 10 cm, so the radius is 0.05 m. The differential height of the manometer reading is 20 cm, which is 0.2 m.

The cross-sectional area at the throat can be calculated using the formula:

A = π * r²

Substituting the values, we find that A = π * 0.05² = 0.00785 m².

Now we can calculate the discharge flow rate:

Q = 0.975 * 0.00785 * sqrt(2 * 9.81 * 0.2) = X m³/s

To convert the flow rate to liters per minute, we multiply by 60000 (1 m³ = 1000 L and 1 min = 60 s).

The upstream velocity can be calculated using the equation:

V = Q / (A * 0.9)

Where:

V is the velocity in m/s

A is the cross-sectional area at the inlet of the venturi meter

0.9 is the specific gravity of the oil

The cross-sectional area at the inlet can be calculated in the same way as before:

A = π * r²

Substituting the values, we find that A = π * 0.075² = 0.01767 m².

Now we can calculate the upstream velocity:

V = X / (0.01767 * 0.9) = Y m/s

Therefore, the discharge flow rate is X L/min and the upstream velocity is Y m/s.

In addition, the atomic force microscope is a non-destructive imaging technique. It is used in various fields such as life science, material science, and nanotechnology. There are different imaging methods that are available in Atomic Force Microscopy including; 1. Contact Mode Imaging Contact mode imaging is the most straightforward and most widely used imaging mode in AFM. It is used for topographic imaging where the cantilever is continuously touching the sample surface. The tip's vertical position is continually adjusted to keep a constant deflection of the cantilever. Advantages of Contact mode imaging are its high resolution and its sensitivity to various surface features.Disadvantages include; low scanning speed, sample damage due to contact with the tip, and tip wear.2. Tapping Mode ImagingTapping mode imaging, also known as amplitude modulation, is a non-contact imaging mode that uses the oscillation of the cantilever to interact with the sample surface.

The oscillation amplitude is typically 50-100nm, so the tip is repeatedly tapped on and off the sample surface. Advantages of tapping mode imaging include its high imaging speed, non-destructive nature and reduced sample damage, and low tip wear rate. However, a significant disadvantage is that the method has a lower spatial resolution than contact mode imaging.3. Non-Contact Mode Imaging Non-contact mode imaging is a non-destructive imaging mode where the cantilever oscillates at its resonant frequency close to the sample surface without touching it. The interaction force between the tip and the sample is relatively weak, so the method requires a delicate balance to maintain a stable tip-sample distance. Advantages of non-contact mode imaging include its non-destructive nature and high-resolution imaging. Disadvantages include its low imaging speed, the possibility of imaging artifacts due to thermal drift, and tip contamination.In conclusion, Atomic Force Microscopy has various imaging modes, each with its advantages and disadvantages. Researchers need to choose the appropriate imaging mode depending on their research objectives, sample type, and other factors.

The figure represents a circuit consisting of resistors (R₁ and R₂), a capacitor (C), and a voltage source (V). The output voltage waveform is requested.

The circuit shown in the figure is a basic RC (resistor-capacitor) circuit. It consists of two resistors, R₁ and R₂, a capacitor C, and a voltage source V. The resistor R₁ is connected in series with the voltage source, while the resistor R₂ and the capacitor C are connected in parallel.

To understand the output voltage waveform, we need to consider the behavior of the RC circuit. When a voltage is applied to the circuit, the capacitor charges up gradually. The rate at which the capacitor charges depends on the values of the resistors and the capacitance.

Initially, when the circuit is energized, the capacitor is uncharged, and the voltage across it is zero. As time progresses, the capacitor starts to charge up, and the voltage across it increases. The rate of charging is determined by the time constant of the circuit, which is the product of the resistance and the capacitance (R₂ * C).

The output voltage waveform would start at zero and rise exponentially towards the applied voltage (20V in this case) with a time constant of R₂ * C. The time constant is given by the product of R₂ (10 kΩ) and C (4.7 F), resulting in a value of 47 ms.

However, without specific information about the input voltage waveform or the time duration of interest, it is challenging to provide a precise graphical representation of the output voltage waveform. The waveform could be a rising exponential curve or a combination of different components, depending on the specific conditions and the behavior of the circuit over time.

Given: Resistivity of silver at 20 °C is 1.59 x 108 am and electron random velocity is 1.6 x 108 cm/s(

a) (i) mean free time between collisions. For the given resistivity of silver, ρ=1.59 x 10⁻⁸ Ωm and electron random velocity is given as u=1.6 x 10⁸ cm/s. The formula for mean free time is given asτ = (m*u)/(e²*n*ρ) Where m is the mass of an electron, e is the charge on an electron and n is the number density of silver atoms.

We know that, m = 9.11 x 10⁻³¹ kg (mass of electron)e = 1.6 x 10⁻¹⁹ C (charge on electron)

For silver, atomic weight (A) = 107.87 g/mol = 107.87/(6.022 x 10²³) kg

Number density, n = (density of silver)/(atomic weight x volume of unit cell)= 10.5 x 10³ kg/m³/(107.87/(6.022 x 10²³) kg/m³)= 5.86 x 10²⁸ atoms/m³

Substituting the given values, we getτ = (9.11 x 10⁻³¹ kg * 1.6 x 10⁸ cm/s)/(1.6 x 10⁻¹⁹ C)²(5.86 x 10²⁸ atoms/m³ * 1.59 x 10⁸ Ωm)τ = 40.6 x 10⁻¹⁵ s≈ 4.06 x 10⁻¹⁴ s

Therefore, the mean free time between collisions is 4.06 x 10⁻¹⁴ s.

(ii) mean free path for free electrons in silver.

The mean free path of electrons is given byλ = (u*τ)where u is the average velocity and τ is the mean free time between collisions.

Substituting the given values, we getλ = (1.6 x 10⁸ cm/s * 4.06 x 10⁻¹⁴ s)≈ 6.5 x 10⁻⁶ cm≈ 6.5 x 10⁻⁸ m

Therefore, the mean free path for free electrons in silver is 6.5 x 10⁻⁸ m.

(iii) electric field when the current density is 60.0 kA/m².

The formula for current density is given by J = n*e*u*E Where n is the number density of electrons, e is the charge on the electron, u is the drift velocity and E is the electric field.

Substituting the given values of resistivity and current density, we can get the electric field. E = J/(n*e*u)

We know that, m = 107.87 g/mol = 107.87/(6.022 x 10²³) kg (atomic weight of silver)n = (density of silver)/(atomic weight x volume of unit cell) = 5.86 x 10²⁸ atoms/m³e = 1.6 x 10⁻¹⁹ C (charge on an electron)

From Ohm's law, we know that J = σ*E Where σ is the conductivity of silver.

Substituting the given values, we get60 x 10³ A/m² = σ*Eσ = 1/ρ = 1/1.59 x 10⁸ Ωm

Substituting the value of σ in the formula for J, we get60 x 10³ A/m² = (1/1.59 x 10⁸ Ωm) * E

Thus, E = 9.54 V/m

Therefore, the electric field when the current density is 60.0 kA/m² is 9.54 V/m.

(b) Differences between drift and diffusion current

Drift current: It is the current that flows in a conductor when an electric field is applied to it. The drift current arises due to the motion of free electrons due to the electric field. The drift current is proportional to the electric field and the number density of free electrons in the conductor.

Diffusion current: It is the current that arises due to the concentration gradient of electrons in the conductor. The diffusion current arises due to the motion of electrons from the region of high concentration to the region of low concentration. The diffusion current is proportional to the gradient of electron concentration and the diffusion coefficient of the conductor.

Par Worksheet 13-2 16361 deals with current in parallel circuits. The current in a parallel circuit is shared between different branches of the circuit.

The total current in a parallel circuit is equal to the sum of the currents in the individual branches. The current through each branch of the parallel circuit depends on the resistance of that branch and the applied voltage. In this case, the circuit contains seven different branches, each with its own current value.

The given circuit diagram shows that the ammeter A is connected in series with the parallel combination of branches BCDEFG. The voltage applied to the circuit is 90 VDC. Using Kirchhoff's current law, we know that the total current in the circuit will be equal to the sum of the currents in each branch. Therefore, current at A + current at B + current at C + current at D + current at E + current at F + current at G = total current in the circuit.

From the circuit diagram, we can calculate the current in each branch using Ohm's law. Let's calculate the current in each branch. At A, the current is not given, so we will calculate it using Ohm's law. The resistance of the resistor connected to point A is 2.5 kΩ.

The voltage applied to the circuit is 90 VDC. Therefore, current at A = voltage at A / resistance of A = 90 / 2500 = 0.036 A = 36 mA.The current at B is 0. The current at C is also not given. The resistance of the resistor connected to point C is 30 kΩ. The voltage applied to the circuit is 36 VDC. Therefore, current at C = voltage at C / resistance of C = 36 / 30000 = 0.0012 A = 1.2 mA.The current at D is not given. The resistance of the resistor connected to point D is 80 kΩ.

The voltage applied to the circuit is 36 VDC. Therefore, current at D = voltage at D / resistance of D = 36 / 80000 = 0.00045 A = 0.45 mA.The current at E is not given. The resistance of the resistor connected to point E is 12 kΩ.

The voltage applied to the circuit is 12 VDC. Therefore, current at E = voltage at E / resistance of E = 12 / 12000 = 0.001 A = 1 mA.The current at F is not given. The resistance of the resistor connected to point F is 10 kΩ. The voltage applied to the circuit is 40 VDC. Therefore, current at F = voltage at F / resistance of F = 40 / 10000 = 0.004 A = 4 mA.The current at G is not given.

The resistance of the resistor connected to point G is 5 kΩ. The voltage applied to the circuit is 40 VDC. Therefore, current at G = voltage at G / resistance of G = 40 / 5000 = 0.008 A = 8 mA.Therefore, current at A = 36 mA, current at B = 0, current at C = 1.2 mA, current at D = 0.45 mA, current at E = 1 mA, current at F = 4 mA, and current at G = 8 mA.

For the two given applications, the electrical engineer needs to select either a Star-Star connected transformer or a Delta-Star connected transformer. In the case of an isolation transformer for an application within the building and a power distribution step-down transformer of 11kV/380V, the appropriate transformer configuration will be suggested with justification.

a) For the isolation transformer within the building, the preferred configuration would be a Delta-Star connected transformer. The Delta configuration provides a greater level of isolation between the primary and secondary sides. This is beneficial in situations where electrical isolation is crucial, such as in sensitive equipment or for safety reasons. The Delta configuration also offers better fault tolerance and can handle unbalanced loads more effectively.

b) For the power distribution step-down transformer of 11kV/380V within the building, the suitable choice would be a Star-Star connected transformer. The Star configuration provides a neutral connection on the secondary side, which is important for distributing power to multiple loads. It allows for the handling of unbalanced loads more efficiently and provides a more stable voltage at the distribution point. The Star-Star configuration is commonly used for step-down transformers in power distribution systems.

In both cases, the selection of the transformer configuration is based on the specific requirements of the application. The Delta configuration offers better isolation and fault tolerance, while the Star configuration provides a neutral connection and efficient handling of unbalanced loads.

For an RL low-pass filter with a cutoff frequency of 4 kHz and R = 10 kΩ, the calculated values are: Inductor (L): 0.25 H, Impedance (Z) at 25 kHz: 0.158 kΩ, Phase angle (φ) at 25 kHz: -80.5°

The correct answer is L = 0.25 H, 0.158 kΩ, and <-80.5°

A low-pass filter is a circuit that eliminates or reduces high-frequency signals while allowing low-frequency signals to pass through unaffected. A low-pass filter is made up of a resistor and an inductor.

To calculate the filter, the formulae L = R/ωC can be used where L is the inductance of the inductor, R is the resistance of the resistor, and ωC is the angular frequency. The formula for calculating the cutoff frequency of a low pass filter is given as;fc= 1/2πRC.

Let's solve for (a) L: fc = 4 kHz = 4000Hz; R = 10 kΩ = 10,000 Ω.

Therefore;fc = 1/2πRL;

L = 1/2πRfc

Using the above equation, let's calculate the value of L:

L = 1/2 × 3.14 × 4,000 × 10,000 = 0.25 H

To calculate the (b) and (c) parts of the question, we need to use the formulas below:

For (b): The magnitude is given as; |Z| = √(R² + ω²L²)

For (c): The phase angle is given as; φ = -tan⁻¹(ωL/R)

The value of |Z| at 25 kHz: |Z| = √(R² + ω²L²);

At 25 kHz, ω = 2πf = 2π × 25,000 = 157,080;

R = 10 kΩ = 10,000 Ω;

L = 0.25 H

|Z| = √(10000² + (157080² × 0.25²));

|Z| = 28762.77 Ω.

The value of φ at 25 kHz: φ = -tan⁻¹(ωL/R);

φ = -tan⁻¹(157080 × 0.25/10000);

φ = -80.54°;

Rounding off to one decimal place gives us φ = <-80.5°.

Therefore, the solution to the question is:L = 0.25 H, 0.158 and <-80.5° O.
