Question

9. State and explain any three properties of a conductor.
​

Answer 1

Answer:

A conductor of electricity is a material or substance which allows to flow of electric current when subjected to a potential difference. This electric current is continue to flow till the potential deference exists. For a given potential difference, the density of electric current in conductor represents how efficient a conductor is. Based on the resistivity the conductors can be classified into two categories i.e. low resistivity/high conductivity material and high resistivity/low conductivity materials.

This general properties of a conductor are listed below –

In equilibrium condition the conductor exhibits the following properties –

Resistance

Inductance

The electric filed inside the conductor is zero

The charge density inside the conductor is zero

Free charge exists only on the surface of the conductor

At the conductor surface, the electric field is normal to the surface.
