## Capacitor[edit]

A capacitor is an electronic component made from two conducting plates separated by a non conducting dielectric of the dimension :

- Length l
- Area A
- Dielectric Constant

The Capacitance of the Capacitor can be calculated by the formual below

The electronics symbol of a capacitor is shown below
