Charge and discharge of a capacitor





The  Charge and discharge of a capacitor circuit: left) the circuit, right) the Waveforms for voltage input and output.
In the previous RC Charging and Discharging tutorials, we saw how a capacitor has the ability to both charge and discharges itself through a series connected resistor.
