Capacitance is a function of the effective area of the
conductors, the separation between the conductors, and the
dielectric strength of the material.
A change in capacitance can be brought about by varying
any one of the three parameters.
- Changing the distance between the two parallel electrodes.
- Changing the dielectric constant, permittivity, of dielectric
medium .
- Changing the area of the electrodes, A
