1. The problem statement, all variables and given/known data In the circuit shown a resistor of 200k ohm is in series with a capacitor of 500uF and a 9v battery. Switch closed at t=0. What is the electric potential difference across the capacitor and the resistor at t=100? 2. Relevant equations Q=cv Tau=rc Q=q(1-e^t/rc) 3. The attempt at a solution Don't even know with that resistor behind the capacitor. I'm so confused.
