Finding Voltage Across A Resistor in a 1st Order RC Circuit

[Jon08CO]

Homework Statement

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).

Homework Equations

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

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...
