In the circuit given below, the current source is 1 A, voltage source is 5 V, R1 = R2 = R3 = 1 Ω, L1 = L2 = L3 = 1 H, C1 = C2 = 1 F. The current through the voltage source V is _________(a) 1 A(b) 3 A(c) 2 A(d) 4 AThis question was addressed to me during an internship interview.This intriguing question comes from Advanced Problems Involving Complex Circuit Diagram topic in portion Network Theory and Complex Circuit Diagram of Network Theory

Answer»

The CORRECT ANSWER is (d) 4 A

Best explanation: At steady state, the circuit BECOMES,

∴ The current through the voltage SOURCE V= 5 – 1 = 4 A.
