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 on an electrically charged particle $p$ at a given point
 * $q$ denotes the electric charge on $p$
 * $\mathbf F$ denotes the force exerted on $p$ by $\mathbf E$.

It is a vector quantity.

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