Capacitance refers to the ability of an object or system to store electric charge. It is determined by the geometry and materials used in constructing capacitors.
A dielectric is an insulating material placed between capacitor plates to increase its capacitance.
Farad: Farad is the unit used to measure capacitance. One farad represents one coulomb per volt.
Charging and Discharging: Charging refers to storing electric charge in a capacitor, while discharging refers to releasing stored charge from it.
