What a capacitor
Charging of a Capacitor. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then. The potential difference across resistor = IR, and. The potential difference between the plates of the capacitor = Q/C.
