Question

In the circuit shown below, switch K is moved from position to position 2 at time t = 0. At time t = 0-, the current in the inductor is I0 and the voltage at the capacitor is V0. The inductor is represented by a transform impedance _________ in series with a voltage source __________

(a) Ls, L V0

(b) Ls, LI0

(c) 1/Ls, LI0

(d) 1/Ls, L V0

The question was posed to me in unit test.

The above asked question is from Series and Parallel Combination of Elements in portion S-Domain Analysis of Network Theory

Answer 1

Correct option is (a) Ls, L V0

For explanation I would say: The inductor has an initial current I0. It is represented by a transform impedance Ls in series with a voltage source L V0.
