Quick Answer: Why there is no electric field around a current carrying conductor?

Why current carrying conductor has no electric field?

The electric field inside a current carrying conductor is zero be because the charges are distributed on the surface of the conductor. … The moving charges create a magnetic field around the conductor. The magnetic field lines around a straight current carrying conductor are in the shape of concentric rings.

Why is electric field intensity inside a conductor zero?

We know that electric field intensity is defined as the force per unit charge. The electric field intensity inside a charged conductor is zero because there are no electric lines of force within the conductor.

What is the electrostatic field due to charge in current carrying conductor?

The major effect on the electric field outside the wire is due the same charges that produce electric field inside the wire – the charges on the surface of the wire. The surface of the wire is a boundary that the charges cannot easily cross so accumulation and excess of charges can persist there.

Can electric field inside a conductor be non zero?

Can the electric field inside a conductor be non 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.

Why is the electric field inside a hollow sphere zero?

According to Gaussian’s law the electric field inside a charged hollow sphere is Zero. This is because the charges resides on the surface of a charged sphere and not inside it and thus the charge enclosed by the guassian surface is Zero and hence the electric field is also Zero.

When a conductor is held in an electric field the field inside the conductor is always?

The “NET” Electric field inside a “conductor” is always zero as you have said. This is basically due to the presence of a lot of free electrons in the conductor. Let us consider a conducting plate kept in a uniform electric field perpendicular to the plane of the conductor as shown.
