This page is all about the Electric Field due to a Point Charge.

Electric Field

Electric Field of two uniformly charged disks: A Capacitor

The Electric Field of a Capacitor can be found by the formula:

Electric field near the center of a two-plate capacitor

[math]\displaystyle{ \ E=\frac{Q/A}{epilson_0} \text{One plate has charge +Q and other plate has charge -Q; each plate has area A; Direction is perpendicular to the plates. Assumption: separation between capacitor is very small compared to the area of a plate. } }[/math]

Fringe Field (just outside the plates near center of disk)

[math]\displaystyle{ \ E_{fringe}=\frac{Q/A}{2epilson_0}\frac{s}{R} \text{s is the separation between plates; R is the radius of plate } }[/math]
