directed from point to point then it will exert a force on a charge moving from to . Work will have to be done on the charge by a force to make it move to against the opposing force of the electric field. Thus the electrostatic potential energy of the charge will increase. So the potential at point is higher than at point . The electric field at any point is the gradient (rate of change) of the electrostatic potential :
:Since there can be
