1. The problem statement, all variables and given/known data

For the RC Circuit (R = 100 Ohm, C = 100 Micro Farads, and an open switch at t=0), we know that the capacitor is charged to a voltage of 10 V prior to T=0.

Find expressions for Vc(t) and Vr(t).

2. Relevant equations

Vc(t) = Vi * e(-t/rc)


3. The attempt at a solution

Vc(t) = 10e^(-100t)
Vr(t) = I have no clue and believe me I have spent a lot of time on this...

Hai, use kirchoff's voltage law to find voltage across resistor
