- A conductor is a material that allows electricity or heat to flow through it easily.

- Conductors have low resistance to the movement of electric charges or heat.

- Examples of conductors include metals such as copper, aluminium, and silver, as well as some liquids (such as saltwater) and gases (such as plasma).

Insulator:

- An insulator is a material that does not allow electricity or heat to flow through it easily.

- Insulators have high resistance to the movement of electric charges or heat.

- Examples of insulators include materials such as rubber, plastic, glass, and ceramics.
