Definition:Electric Field Strength

Definition
Electric field strength is the measure of the intensity of an electric field.

It is defined as:
 * $\mathbf E = \dfrac {\mathbf F} q$

where:
 * $\mathbf E$ denotes the electric field strength at a given point
 * $\mathbf F$ denotes the force exerted on a test charge $q$ by $\mathbf E$ at that point.

Electric field strength is a vector quantity.

Also known as
Some sources give this as electric field intensity.
