with the help of examples explain the uses of a conductor and an insulator
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
- Conductors conduct electrical current very easily because of their free electrons.
- Insulators oppose electrical current and make poor conductors.
- Some common conductors are copper, aluminum, gold, and silver.
- Some common insulators are glass, air, plastic, rubber, and wood.
