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 the voltage source V is _________

(a) 1 A

(b) 3 A

(c) 2 A

(d) 4 A

I had been asked this question in my homework.

I need to ask this question from Calculation of I(0+), di/dt(0+), d2I/dt2(0+) in Circuits Involving both Capacitor and Inductor topic in division Application of the Laplace Transform in Circuit Analysis of Network Theory

Answer 1

The correct option is (d) 4 A

To explain: At steady state, the circuit becomes,

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