This is the principle of capacitors. The amount of charge that can be stored is referred to as capacitance, and capacitance ‘C’ is determined by permittivity ‘ε’ of the insulator, surface area ‘S’ of the electrodes, and thickness ‘d’ of the insulator.
Capacitor Definition: A capacitor is defined as a device with two parallel plates separated by a dielectric, used to store electrical energy. Working Principle of a Capacitor: A capacitor accumulates charge on its plates when connected to a voltage source, creating an electric field between the plates.
Charging and Discharging: The capacitor charges when connected to a voltage source and discharges through a load when the source is removed. Capacitor in a DC Circuit: In a DC circuit, a capacitor initially allows current flow but eventually stops it once fully charged.
The behaviour of a capacitor in DC circuit can be understood from the following points − When a DC voltage is applied across an uncharged capacitor, the capacitor is quickly (not instantaneously) charged to the applied voltage. The charging current is given by, i = dQ dt = d(CV) dt = CdV dt (2)
So, it can be said that initially a capacitor is short-circuited and finally open circuited when it gets connected across a battery or DC source. Suppose a capacitor is connected across an AC source. Consider, at a certain moment of positive half of this alternating voltage, plate-I gets positive polarity and plate-II negative polarity.
