Physics II Image: Kirchoff's Laws RC Circuit Quizzes Image

Because Canvas is so bad at copying images, here is another quiz image:

This circuit contains a battery with EMF ε and internal resistance r, which is connected to a capacitor of capacitance C and a resistor in series with the capacitor with series resistance R_S, and another resistor in parallel with the first resistor and capacitor with resistance R_P. There is a switch which can be open (shown) to allow the capacitor to discharge through the resistors R_S and R_P, or it can be closed to allow the capacitor to charge from the battery through the resistors r and R_S.

Bonus Images:
Switch open for discharging the capacitor

Switch closed for charging the capacitor

Some neat questions can come from these.
