A capacitor uses an electric field to store the potential electric energy which can be used as a power source when connected to a network.
A capacitor is characterized as a latent part which is utilized for putting away electrical energy. A capacitor is made of two conduits that are isolated by the dielectric material. These dielectric materials are as plates which can aggregate charges. One plate is for a positive charge while the other is for a negative charge.
The energy put away in a capacitor is only the electric possible energy and is connected with the voltage and charge on the capacitor. In the event that the capacitance of a guide is C, it is at first uncharged and it obtains a potential distinction V when associated with a battery. In the event that q is the charge on the plate around then,
q=CV
Therefore,Work done=Vdq
=>dW=(q/C)dq
=>dW=[tex]\int\limits^q_ 0[/tex](q/C)dq
=>dW=(1/2)q²/C
