Potential gradient

A potential gradient is the local space rate of change of the potential.

In electrostatics then, it is the local space rate of change of the electric potential:


 * $$\mathbf{E} = - \delta V / \delta s$$

Units are volts per meter (V/m). The electric field is the same as the potential gradient but with opposite sign.

In biology, potential gradient is the net difference in electric charge across a cell membrane.
