Capacitance of a Parallel Plate Capacitor

Parallel plate capacitor consists of two conducting plates parallel to each other and separated by a distance which is small compared  with  the dimensions of the plate.

Let A be the area of each plate separated by a distance d in vacuum and +q and -q are the charges given to the plates.

The charges on each plate are attracted by the charges on the other plate. So the charges spread out uniformly on the inner surfaces of the plates and produce an electric field E between the two plates. Continue reading “Capacitance of a Parallel Plate Capacitor”
