Electricity Doubt: Is Electric Field Inside Conductor?

[prashant3507]

it is true that no electric field exists inside a conductor but still when we use wire(a conductor)in electric circuits electric field exists inside it.

The statement that the electric field inside a conductor is zero is only true in the electrostatic case. Within a current-carrying conductor there are moving charges and a non-zero electric field.

Thank you for bringing up this interesting topic. While it is true that no electric field exists inside a conductor in electrostatic equilibrium, the situation is different in the case of electric circuits. In an electric circuit, the conductor (such as a wire) is not in a state of electrostatic equilibrium, as there is a flow of electric current through it.

This flow of current creates a magnetic field around the wire, which in turn induces an electric field inside the wire. This induced electric field is responsible for the movement of electrons through the wire, and it is this movement of electrons that we observe as electric current. Therefore, even though there is no electric field inside the conductor in electrostatic equilibrium, there is an induced electric field inside the wire in an electric circuit.

Additionally, the presence of impurities or defects in the conductor can also lead to the presence of electric field inside the conductor. These impurities can act as barriers for the flow of electrons, causing them to accumulate in certain areas and creating an electric field.

In conclusion, the statement that no electric field exists inside a conductor is only valid in the case of electrostatic equilibrium. In the case of electric circuits, there is an induced electric field inside the conductor, and the presence of impurities can also lead to the existence of electric field inside the conductor.
