- Allow electric current to flow through them easily.

- Have a low resistance to the flow of electric current.

- Examples include metals such as copper, aluminium, and gold.

Insulators

- Do not allow electric current to flow through them easily.

- Have a high resistance to the flow of electric current.

- Examples include rubber, plastic, and wood.

The main difference between conductors and insulators is the ease with which they allow electric current to flow through them. Conductors have a low resistance to the flow of current, while insulators have a high resistance. This difference is due to the different atomic structures of conductors and insulators. Conductors have atoms with loosely bound electrons, which can easily move from atom to atom, while insulators have atoms with tightly bound electrons, which cannot easily move.

Conductors are used in electrical wiring, because they allow current to flow easily. Insulators are used to prevent current from flowing where it is not wanted, such as around the outside of electrical wires.
