Electrostatic Potential and Capacitance

Question:
What type of surface is the surface of a conductor?
Options:
Equipotential
Unipolar
Exopotential
Bipolar
Correct Answer:
Equipotential
Explanation:
Electric field at any point is equal to the negative of the potential gradient. But inside a conductor, the electric field is zero. Hence, the electric potential is constant throughout the volume of a conductor and has the same value on its surface. Thus the surface of a conductor is equipotential.
