Homework Statement
Find the expression of the current "i" by terms of time.
The answer is 3e^(20t) Amps
Homework Equations
i(t)=I_final+(I_initial-I_final)*e^(-t/τ)
The Attempt at a Solution
I have found the initial current as 3 amps. However, after the switch had been changed for too long, I m not sure about the way how the inductor behaves. Will it be a short circuit? If so, there is some problem about the loop on the right, like 8ix-6ix=0
Can the dependant source behave like that? Also I have problem about finding the time constant, I find 1/τ as 60.
Thanks for your help!
