Question

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 R3 is _________

(a) 1 A

(b) 5 A

(c) 6 A

(d) 8 A

The question was posed to me in an internship interview.

This intriguing question comes from Advanced Problems Involving Complex Circuit Diagram topic in division Network Theory and Complex Circuit Diagram of Network Theory

Answer 1

The correct answer is (b) 5 A

For explanation: At steady state, the circuit becomes,

∴ The current through R3 = \(\frac{5}{1}\) = 5 A.
