Dingfeng Capacitor------Principle of Capacitor

It is a device used to store charge in an electrical circuit

An every day use

To remove sparking in the ignition system of an automobile. When an electric current is switched on or off there is an induced current which can create sparking. If we put a capacitor in the circuit this current charges the capacitor instead and this will avoid occurrence of sparking.

Charge is proportional to potential

When a charge is given to a conductor its potential rises. If we give a conductor a charge Q then its potential rises. The greater the charge the greater the potential. So they are proprotional to each other and may be exepressed as

Q ∝ V

Which means that charge Q is directly proportional to potential V or that the potential is directly proportional to the charge given to a conductor

We can re-write this as the following equation

Q = C V

Here C is the capacitance of the conductor

Factors determining Capacitance

1. Shape and size of the conductor

2. The surrounding medium

3. Presence of other conductors

We can re-write the equation as:

C=Q/V
