The charge and discharge of a capacitor

The rate at which a capacitor can be charged or discharged depends on: (a) the capacitance of the capacitor) and (b) the resistance of the circuit through which it is being charged or is discharging. This fact makes the capacitor a very useful if not vital component in the timing circuits of many devices from clocks to computers.

6 FAQs about [What is the essence of capacitor discharge]

What happens when a capacitor is fully discharged?

As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls. Eventually the charge on the plates is zero and the current and potential difference are also zero - the capacitor is fully discharged.
