## Is the electric field on the surface of a conductor constant?

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. Outside the conductor, the field is identical to that of a point charge at the center equal to the excess charge.

## Why is electric potential continuous across the surface of a charged conductor?

The potential is constant inside and outside the conductor. As it is 0 inside the conductor due to the absence of any field line and outside the sphere, though the field lines are discontinuous but the potential is continuously present.

## Is the electric field only discontinuous at the surface of a conductor?

We know that electric field is discontinuous across the surface of a charged conductor. Electric potential is not discontinuous across the surface of a charged conductor. … Since, electric potential is a scalar quantity and, does not have to represent directions, it is continuous at every point.

## Why electric field is normal to the surface of a 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.

## Can electric field pass through a conductor?

The net electric field inside a conductor is zero. Therefore, the electric field lines do not pass through a conductor.

## Why can electric fields not cross each other?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

## Is electric field continuous across a charged conductor?

We know that electric field is discontinuous across the surface of a charged conductor.

## Why electric field is not continuous?

Electric field lines are continuos curves. They start from a positively charged body and ends at a negatively charged body. No electric lines of force exist inside the charged body. Thus electrostatic field lines are continuous but do not form closed loops.

## Which among the following electric field potential is discontinuous across the surface of a charged conductor?

Electric field is discontinuous across the surface of charged conductor.

## Is electric field continuous or discontinuous?

We know that electric field is discontinuous across the surface of a charged conductor.

## Is the electric field continuous?

Electric field lines are continuous because they are imaginary lines or you can call it the locus of a curve. We know electric filed is a vector. And the imaginary filed lines are drawn in a certain way such that when we draw tangent at any point on the curve, then it will give the direction of electric field.

## Which fields are discontinuous at boundary?

Explanation: The normal component of an electric flux density is always discontinuous at the boundary for a dielectric-dielectric boundary. We get Dn1 = Dn2, when we assume the free surface charge exists at the interface.

## Why do electric field lines never form closed loops?

If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. … Therefore, we say electrostatic field lines never form closed loops.

## Why does potential decrease in electric field?

If a charge is moving in the direction that it would normally move, its electric potential energy is decreasing. If a charge is moved in a direction opposite to that of it would normally move, its electric potential energy is increasing.
