Electric field strength

From Glossary of Meteorology



electric field strength

(Also called electric field, electric intensity, electric field intensity, electric potential gradient, field strength, and probably others.) The electrical force exerted on a unit positive charge placed at a given point in space.

The electric field strength is expressed, in the mks system of electrical units, in terms of volts per meter and is a vector quantity. The electric field strength of the atmosphere is commonly referred to as the atmospheric electric field.
