Back

A pathway through which electricity flows.

Front

What is an insulator?

Back

A material through which heat or electricity does not easily flow.

Front

What is a closed circuit?

Back

Back

A pathway that prevents electric current from flowing freely or that stops the flow.

Front

What is a conductor?

A material that allows heat or an electric current to flow through easily.

Front

What happens in a closed circuit?

Back

Electric current flows freely through the circuit.

Front

What happens in an open circuit?

Back

Electric current is stopped and cannot flow.

Front

Can an insulator conduct electricity?

Back

No, an insulator does not allow electricity to flow.
