Question

In the following circuit, steady state exists when switch S is in position 1. At t=0, it is moved to

position 2. Obtain the expression for current using Laplace transformation​

Answer 1

A::B::C

Solution :

Let

be the initial current in the steady state condition before shifting the swith.

<br> Let

be the current in the circuit at time

<br> Since the flux associated with inductors will be same just before and after the shifting of switch, (otherwise the induced
