If no changes are made to this circuit, what will the results be?

• Both bulbs are off because the switch is open

• Only the left bulb is lit because it has a closed path. The right bulb is not lit because of the open switch

• Both bulbs are lit because they each have a complete, closed path to the battery

• Only the right bulb is lit because an open switch causes the energy to flow to the bulb.

This circuit has five light-emitting diode, or LED, lights. It also has one battery and one switch. Which LEDs produce light when the switch is in the position shown? (5.6B)

• LEDs 1, 3, and 4 only

• LEDs 1, 2, 3, and 4

• LEDs 3 and 4 only

• LEDs 1, 3, 4, and 5
