A dime is made of copper and nickel, both of which are conductors of electricity.

Here's why:

* Conductors allow electricity to flow through them easily. This is because they have free electrons that can move throughout the material.

* Insulators resist the flow of electricity. They have tightly bound electrons that don't move easily.

Since copper and nickel have free electrons, they allow electricity to flow through them, making a dime a conductor.
