Question 1
A series RLC circuit has resistance R = 10 ohms, inductance L = 0.1 H, and capacitance C = 10 microfarads. What is the resonant frequency (f_r) of the circuit and its quality factor (Q)?
Correct Answer:
159.2 Hz, 10.0
Question 2
In a linear active bilateral network, the open-circuit voltage across two terminals is 24 V. When a 12 ohm resistor is connected across these terminals, the voltage drops to 16 V. Find the Thevenin equivalent resistance (R_th) of the network.
Correct Answer:
6 ohms
Question 3
An AC voltage source with an internal impedance of Z_s = (8 + j6) ohms delivers power to a load. For maximum power transfer to the load, what must be the load impedance (Z_L)?
Correct Answer:
8 - j6 ohms
Question 4
A DC voltage source of 10 V is applied to a series RL circuit with R = 5 ohms and L = 2 H at t = 0. What is the expression for the current i(t) for t >= 0?
Correct Answer:
i(t) = 2(1 - e^(-2.5t)) A
Question 5
A symmetric T-network has series arm resistances R1 = R2 = 4 ohms, and a shunt arm resistance R3 = 10 ohms. Find the open-circuit impedance parameters Z_11 and Z_12 of this two-port network.
Correct Answer:
Z_11 = 14 ohms, Z_12 = 10 ohms
