Hi, in part b when t>0 the capacitor is replaced by an open circuit , however in part c the capacitor is replaced by a short circuit why is that?Aren't inductors the only ones...
I was referring to these two circled resistors, don't they have the same voltage because they are in parallel? I found the io using current divider io=(40/50)(8e^-250t), then use that io to find vo with ohms law.
I think I got it. I did Current divider io= 40/40+10 (8e^-250t) . I got 6.4e^-250t Amps then using Ohms law with the 10ohm resistor I got 64e^-250t V can someone confirm it please?

Could someone explain me what happened in the step that is circled in red please? I would appreciate it.
did they multiply i0x(iL)?
Homework Equations
they got iL by using iL=iL(initial)*e^-t/Tau . How did they get Vo? what...
