Question

practice it!
harley was creating a model of a working circuit. when he made his model, he realized the bulb was not lit. a picture of harleys model is shown here.
select the statement that accurately explains why the bulb was not lit.
he had two working batteries.
all of the wires were connected.
the wires were connected to the correct ends of the battery.
the switch on his circuit was open.

Explanation:

For a bulb to light in a circuit, the circuit must be closed (complete). If the switch is open, the circuit is incomplete, and current cannot flow, so the bulb won't light. Having two working batteries (if connected properly) would provide more power (but not the reason for not lighting here). All wires connected (if circuit is open at switch - still no current). Wires connected to correct battery ends (if switch is open - no current).

Answer:

The switch on his circuit was open.
