Question

I want to check if my answer is correct

for a)

I got 2mA(1 - e-t/1us) for iL, and 20V(1 - e-t/1us) for VL

for b)

I got 2mA(e-t/0.5us) for iL, and -40V(e-t/0.5us) for VL

then after doing t = 5T in question B

In iL, I got 13.48uA

and In VL, I got -269.52mV

Is this correct, if so how can I make a wave for in part C?
