Question

In the circuit shown below, the switch is closed at t = 0, applied voltage is v (t) = 50cos (102t+π/4), resistance R = 10Ω and capacitance C = 1µF. The current flowing in the circuit at t = 0 is? (a) 1.53 (b) 2.53 (c) 3.53 (d) 4.53 This question was addressed to me during an interview for a job.

Answer 1

The correct option is (c) 3.53 The best I can explain: At t = 0 that is initially current flowing through the circuit is i = V/R cosθ = (50/10)cos(π/4) = 3.53A.
