Under electrostatic conditions electric field inside a conductor is zero but in electrodynamic condition the field is not equal to zero,how field develop inside a conductor in electrodynamic condition.
Find out the relationship between the electric field and electric potential include which of the following statement?
I. If the electric field at a certain point is zero, then the electric potential at the same point is also zero.
II. The electric potential is inversely proportional to the strength of the electric field.
III. If the electric potential at a certain point is zero, then the electric field at the same point is also zero.
