Choose the best answer for what a DC blocking or coupling capacitor does, assume the capacitor value is chosen to be too small.
Blocks the DC and is relatively high impedance to the AC voltage. Blocks only the AC voltage going into the next stage Blocks the DC voltage going into the next stage, but lets the AC signal go through Has a variable voltage gain and blocks the DC level Works well with a BJT transistor only
an electric motor operates at 220V rms ,60 Hz, draws 20A rms, and has a power factor of 0.75 lagging. a) what is average power absorbed by the motor b) what value capacitor should be connected in parallel with the motor to give a power factor of 1
Semiconductor A is direct band gap and semiconductor B is indirect gap. For providing same short circuit current density of a solar cell, which material will need more thickness
A shunt motor has the following ratings: 75 kW, 240 V, 1750 rpm, 300 A. The motor is supplied with 240 V source (constant) at its armature terminals. Its armature resistance is 0.0144 [O]. At rated current Ia = 300 A, the motor runs at rated speed..
Given the characteristic equation: F(z) = z^3 + z^2 + kz - 0.5 = 0 a) Use the Jury test to determine the range of "k" that ensures the system is BIBO stable. Show any inequality graphs and how they are combined to determine the valid range of k.
A switch closes at t=0 and the capacitor is discharged through the wire with 1 Ohm resistance. Find the expression for the magnetic field strength inside the capacitor 1 cm from the axis as a function of time. Draw the graph of B versus t.
How does the placement location of ECG leads affect the signal measured Why is the placement of ECG leads on the wrists equivalent to placing them on the chest
What happens if R was infinite in parallel RLC circuit and What happens if R was zero in parallel RLC circuit what will be the circuits can we still apply the neper frequency now which will be zero
A signal is sampled every 1ms for 20ms, with the following actual values of the analogue voltage at successive sampling times. Plot the values of the voltage recorder by a 5 volt, 4 bit ADC assuming that the noise level is much lower
A current generated in the stack and a stack voltage of 6.0 V. As an engineer, you have a choice to install a recirculation pump to recycle the unused hydrogen from the anode exhaust back into the anode to increase the effective fuel utilization t..
A storage tank has a Diameter of 20ft and a height of 10ft. The output volumetric flow from this tank is given by fout(t)=2h(t) where h(t) is the height of the liquid in the tank. At a particular time the tank is at steady state with an input flow..
Explain the conditions of diode in forward and reverse biased?
It involves developing a function called "single_phase_transformer_tests" that can work on user input data to generate the transformer voltage regulation and efficiency under various loading criteria.
