Potential gradient
From Wikipedia, the free encyclopedia
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:
- <math>\mathbf{E} = - \delta V / \delta s</math>[1]
Units are volts per meter (V/m). The electric field is the same as the potential gradient but with opposite sign.
In biology, the net difference in electric charge across a cell membrane.
