Electric field
From Computer History Wiki
(Redirected from Electrical field)
The electric field is one of the five fundamental fields that pervade space, along with magnetic, strong, weak and gravitational fields - although electricity and magnetism have been considered two aspects of one more fundamental field since the late 1800's.
At every point in space, the electric field has a value which is a vector, i.e. a strength and a direction.
The electric field can exert a force on a charged entity, such as an electron. This effect is used in many ways, including in semiconductor devices of all kinds, and in CRTs (which use beams of electrons).
