Question

choose the correct answer.
in this simple circuit,
the light bulb is off.
what must happen
in order for the light
bulb to turn on?
the switch will have to be closed
the battery will have to be removed

Explanation:

Step1: Analyze the circuit

A circuit needs to be complete (closed) for current to flow. When the switch is open, the circuit is broken, and no current reaches the light bulb.

Step2: Consider the effect of closing the switch

Closing the switch completes the circuit. Current can then flow from the battery, through the wire, and light up the bulb.

Step3: Analyze removing the battery

Removing the battery would remove the power source. The bulb would definitely not light up.

Answer:

the switch will have to be closed
