When a wire becomes disconnected from the circuit, what do we then call that circuit?

• a series circuit

• a parallel circuit

• an open circuit

• a closed circuit

Identify why it’s necessary for the metal parts of the wires to touch the metal parts of the battery and receiver/load.

• Because the metal is a conductor and allows the electricity to flow easily through

• Because the metal is a conductor and stops the flow of electricity

• Because the metal is an insulator and allows the electricity to flow easily through

• Because the metal is an insulator and stops the flow of electricity
