When electric field inside a conductor is not zero?

The answer is NO. Electric field inside a conductor is always zero. Reason: The electricity conducting free electrons are only present on the external surface of the conductor. Resultantly, electric field is only present in the external surface of the conductor.

Why is the electric field inside a conductor zero How does the electric field become zero in a conductor?

Due to a large number of electrons, the force of repulsion acting in between them is also very high. Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.

Is the electric potential inside a conductor zero?

Since an electric field requires the presence of a charge, the electric field inside the conductor will be zero i.e., E=0 . Thus the electric potential will be constant inside the conductor.

What is electric field inside a conductor?

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.

Will the electric field always be zero at any point where the electric potential is zero?

(a) No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point. At the midpoint between the charges, the electric field due to the charges is zero, but the electric potential due to the charges at that same point is non-zero.

What is electric field inside the conductor?

Is the electric field inside an insulator zero?

Inside a conductor E=0 everywhere, ρ = 0 and any free charges must be on the surfaces. In an insulator charges cannot move around, and the charge density can have any form. If ρ(r) = 0, the potential is non-uniform, and E = 0 inside the insulator.

Why should electrostatic field inside a conductor?

The electrostatic field should be zero inside a conductor because in a conductor, the charges are present on the surface. Therefore, the charge inside should be zero. Also, according to the Gauss theorem, the electrostatic field is zero.

Why is there no electric field inside a non-conductor?

So, finally there will be no net electric field inside the conductor and thus, there will be no electric field line inside any conductor. For non conductor , there is no free electron , so no charge can be moved inside a non conductor. Thus applying an electric field on a non conductor will generate an electric field inside the non conductor.

What is the free charge inside a conductor?

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.

What happens when electrons are placed on the surface of conductor?

This accumulation of charge on both surface of conductor A and B, will lead to development of Electric Field E’ inside the conductor and this developed electric field E’ will oppose the flow of further electron toward face A.

What is the net force of electric field inside a conductor?

Therefore, net force on electrons = 0 and hence no movement of electrons. Thus we see that at equilibrium, the strength of electric field inside the conductor is zero.
