To learn more about this topic, physics, and the related topics, please take a look at the questions and additional content below. How are lines of force related to equipotential lines? The electric field is zero at equipotential lines. As a result, when the potential is constant, the negative potential also becomes zero, necessitating the need for the electric field to be always present with the surface. That means a uniform electric field is also perpendicular to the equipotential surface. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". the electric field is perpendicular to the conductor and the equipotential lines are parallel to the conductor. When a single point charge has an equipotential surface, the surface is cylindrical in shape. Points A and B are both located at the equator, while points C and D are located at the northern end of the equator. As a result, all surfaces are always at right angles to the lines of electric force. If V and r are constant for a single charge q, potential can be expressed as this. This means there is no change of potential energy so no work is done on the charge. An electric field forms between two surfaces where electric charges are applied if they are placed together.
