Can an electric field continuous across the surface of conductor give reason?

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 If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.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.
