Conductors and Insulators of Electric Energy

Front

What is a conductor of electric energy?

Back

A conductor of electric energy is a material that allows electric current to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator of electric energy?

Back

An insulator of electric energy is a material that does not allow electric current to flow through it easily. Examples include rubber, plastic, and wood.

Front

What is the role of conductors in electrical circuits?

Back

Conductors allow electric current to flow through the circuit, enabling devices to work.

Front

What is the role of insulators in electrical circuits?

Back

Insulators prevent electric current from flowing where it is not wanted, protecting users from electric shock.
