It is a vector quantity.

### Symbol

The usual symbol used to denote electric field strength is $\mathbf E$.

### Dimension

Electric field strength has the dimension $\mathsf {M L T}^{-3} \mathsf I^{-1}$.

### Units

The SI unit for electric field strength can be given either as:

volt per metre: $\mathrm V / \mathrm m$
newton per coulomb: $\mathrm N / \mathrm C$

## Also known as

Some sources give this as electric field intensity.
