Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to flow through it easily. Examples include rubber, glass, and plastic.

Front

Why is a jacket considered an insulator?

Back

A jacket is made of materials that slow down the transfer of heat, keeping the body warm.

Front

What is the role of conductors in electrical circuits?

Back

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

Front

What is the role of insulators in electrical circuits?

Back

Insulators prevent the flow of electricity, protecting users from electric shock.
