Electrical conductivity is the ability
Electrical conductivity is the ability of a material to conduct electricity.
Take an electrical circuit consisting of a bulb, cell, wire and a switch.
Connect wood to the circuit.
The bulb does not glow indicating that wood is a poor conductor of electricity.
Connect a paper roll to the circuit.
The bulb does not glow, indicating that paper is also a poor conductor of electricity.
Take a metal like iron and connect it in the same circuit.
The bulb glows indicating that iron is a good conductor of electricity.
Similarly, other metals like copper, silver, etc. also make good conductors of electricity.
Hence, we can say that most metals are good conductors of electricity.
