what is the value of electric feild inside a conductor
Answers
Answer:
The electric field is zero inside a conductor. Just outside a conductor, the electric field lines are perpendicular to its surface, ending or beginning on charges on the surface. Any excess charge resides entirely on the surface or surfaces of a conductor.
Explanation:
In electrostatics free charges in a good conductor reside only on the surface. So the free charge inside the conductor is zero. So the field in it is caused by charges on the surface. Since charges are of the same nature and distribution is UNIFORM, the electric fields cancel each other. In an insulator the charge distribution in an atom may change, but the charges do not leave their nuclei. When we consider electrostatics, the case where charges are not moving, this definition has several immediate consequences. There can be no electric field inside a conductor.
