Determine the inductor current i(t) for both t < 0 and t > 0 for each of the circuits below.

**In the answers below, use exp() for e^{()}, i.e., exp(5) for e^5.**

###Circuit a

Determine the value of i(t) [in A] at t = 0^-. i(t)=

Enter an expression for i(t) [in A] for t > 0. i(t)=

###Circuit b

Enter the value of i(t) [in A] at t = 0^-. i(t)=

Enter an expression for i(t) [in A] for t > 0. i(t)=
