## Homework Statement

It asks me to find io(t=0

^{-}), io(t=0

^{+}), and Vc(t=0

^{-}). C=100μF R= 2kΩ

## Homework Equations

V=I*R, i(t)= i(∞)+[i(0

^{+})-i(∞)]*e

^{-t/τ}, Vc(0-)=Vc(0+)

## The Attempt at a Solution

[/B]I first tried to calculate Vc(0-) as it will be the same as Vc(0+), stating that at t=0

^{-}the capacitor acts as an open circuit because it's been fully charged (the switch has been off since -∞), and I think it's 24V but I'm not sure about that. I also calculated io(0-), which is 2A, but I couldn't go any further.

Thank you guys.
