Why is the potential inside a conductor constant?

As inside the conductor the electric field is zero ,so no work is done against electric field to bring a charge particle from one point to another. Therefore the potential inside the surface is ZERO.

Why is the potential inside a hollow spherical charged conductor constant?

Electric field intensity is zero inside the hollow spherical charged conductor. So no work is done in moving a test charge inside the conductor and on its surface. Therefore there is no potential difference between any two points inside or on the surface of the conductor.

What can you say about the electrostatic potential throughout the volume of a charged conductor?

as electric field inside the conductor is zero so there is no work done in moving a small test charge within the conductor. therefore there is no potential difference between any two points inside the conductor that is electrostatic potential is constant throughout the volume of the conductor.

Why must electrostatic field be normal to the surface at every point of a charged conductor?

Electric field is defined as the gradient of potential and the surface of a conductor has a constant potential. Therefore, there is no field along the surface of the conductor and hence the electrostatic field at the surface of a charged conductor should be Normal to the surface at every point.

What remains constant inside a conducting sphere?

Electric potential inside a conductor is constant and it is equal to that on the surface of conductor.

Is electrostatic potential necessarily 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 potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero.

Why is the electric field always perpendicular to the surface of a conducting object in electrostatic equilibrium?

The mutual repulsion of excess positive charges on a spherical conductor distributes them uniformly on its surface. The resulting electric field is perpendicular to the surface and zero inside.

What is meant by constant electrostatic potential?

Constant Electrostatic Potential means that no work need be performed for a small positive charge to move from one part of the conductor to another. If at all moving a charge in this manner requires work to be performed. It implies that the conductor has some definite resistance.

What happens if the electrostatic field is not perpendicular to the conductor?

If the electrostatic field lines are not perpendicular to the surface of the conductor, there will be a tangential component of the electric field. If that is the case, it would create a potential difference and would accelerate the free electrons resulting in current.

How does a conductor stay at a constant potential throughout?

The only way a conductor can stay at a constant potential throughout or be an equipotential surface, is if the electric field lines are perpendicular to all elemental surfaces of the conductor.

Why is the electric field inside a conductor zero?

As inside the conductor the electric field is zero ,so no work is done against electric field to bring a charge particle from one point to another. Therefore the potential inside the surface is ZERO. Why is the electric field inside a conductor zero?
