Why is the Electric Field Zero Inside a Charged Conductor?

Answer: A substance with many free electrons accessible for the flow of current is said to be a conductor. Since there are many electrons, they also have a strong force of repulsion. Therefore, the electrons travel to the conductor’s surface to reduce the repulsion among them. Consequently, we can state there is no net charge present within the conductor. Gauss law can be used to understand this mathematically.

Since the conductor is impartial, it attracts a more negative charge to a surface where the electric field applies when positioned inside an electric field.
