What happened when Gary closed the switch?

• The bulb lit, and the buzzer sounded at the same time.

• Nothing happened because light bulbs and buzzers must be in different circuits.

• Nothing happened because there was no source of electrical energy in the circuit.

• Nothing happened because the circuit needed to have two switches.

Jay uses various objects to complete a circuit. He compares how bright a bulb glows using each object. His results are shown here.
