Circuits 5.6B Prequiz

A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?

• Light bulb 1 and light bulb 2 will both be on

• Light bulb 1 will be off, but light bulb 2 will be on

• Light bulb 1 and light bulb 2 will both be off

• Light bulb 1 will be on, but light bulb 2 will be off

 A light bulb changes electrical energy into
