Charge & Discharge Graphs | AQA A Level Physics Revision Notes
The capacitor charges when connected to terminal P and discharges when connected to terminal Q. At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero. As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge
