Design a simple circuit that includes a battery, a switch, and a light bulb. Explain how closing the switch affects the circuit.

• Closing the switch completes the circuit, allowing current to flow and the bulb to light up.

• Closing the switch breaks the circuit, preventing current from flowing.

• Closing the switch has no effect on the circuit.

• Closing the switch reverses the direction of current.
