t<0 the switch is opened.
t=0 the switch is closed. The problem asks for the behaviour
i(t) after closing the switch. I tried to solve it with KVL but result is different from the book. The current
t<0 is 1.73A. So I converted the above circuit to the Laplace domain.
Then I applied KVL and I found a current and
Using the inverse Laplace the result is different from the one in the book wich is found using differential equations in the time domain. Can someone try to solve the circuit? Thanks
