What happens when the switch in an electric circuit is open?

• The current will still flow.

• The circuit becomes a closed loop.

• The current will not flow.

• The voltage across the circuit increases.

What happens when the switch in an electric circuit is closed?

• The current will not flow.

• The circuit breaks down.

• The current will flow.

• The resistance increases.
