electric field is not 0 and potential is 0 example please.
Dear Student,
As we know that electric field has a relation of the directional gradient of electric potential.
so if V is constant, E should be zero. So, for E to be zero, either V has to be zero, or constant. But if V is zero, then surely E has to be zero; the reverse case is not true always.
For example, if you consider the condition can be thought of two identical charges separated by a certain distance(i.e. dipole). In the middle of the two-point charges, the electric field is zero but the potential difference is not zero and has a finite value depending upon the charge and separation of two charges.
Regards,
