1. The problem statement, all variables and given/known data It asks me to find io(t=0-), io(t=0+), and Vc(t=0-). C=100μF R= 2kΩ 2. Relevant equations V=I*R, i(t)= i(∞)+[i(0+)-i(∞)]*e-t/τ, Vc(0-)=Vc(0+) 3. The attempt at a solution 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.
