Electric Field

See Also: Magnetic Field

A region of space characterized by the existence of a Force generated by electric Charge. The strength of an electric field is determined by the Voltage a wire (see Conductor) carries. For example, a stronger electric field exists under a 161,000-volt transmission line than beneath a 13,000-volt Distribution line. These fields remain relatively constant because the voltage also remains relatively constant. Electric fields are easily blocked. For example, electric fields originating from a distribution line are blocked by a house and by the trees between the house and the line.

Electric fields are measured in kilovolts per meter (kV/m).
