Parallel Plate Capacitor • A parallel-plate capacitor is made up of two plates of area A separated by a distance d. The charges on the facing plate surfaces have the same magnitude q but opposite signs. ( b) As the field lines show, the electric field due to the charged plates is uniform in the central region between the plates.

Capacitance - Definition The capacitance of two oppositely charged conductors, C, is defined by C = q / V The capacitance is a measure of how much charge must be put on the plates to produce a certain potential difference between them: The greater the capacitance, the more charge is required. The SI unit of capacitance that follows from C = q/V is the coulomb per volt. This unit occurs so often that it is given a special name, the farad (F):
The capacitance depends only on geometrical factors - namely, the plate area A and the plate separation d . Note that C increases as area A increases or separation d decreases. Gauss Law
