Question

Which list of components creates a circuit through which an electric current can flow?

A. A battery, insulated wires, a buzzer, and an open switch
B. A generator, two light bulbs, and an open switch
C. A generator, a light bulb, and a closed switch
D. A battery, insulated wires, and a buzzer

Answer 1

To create a complete circuit through which an electric current can flow, you need a power source (like a battery or generator), conductive paths (like insulated wires), a load (like a buzzer or light bulb), and a closed switch to complete the circuit.

Let's analyze each option:

A. A battery, insulated wires, a buzzer, and an open switch - The open switch means the circuit is incomplete, so current cannot flow.

B. A generator, two light bulbs, and an open switch - Again, the open switch means the circuit is incomplete.

C. A generator, a light bulb, and a closed switch - This option has a closed switch, which means the circuit is complete. This allows current to flow.

D. A battery, insulated wires, and a buzzer - There is no switch mentioned, and without a switch, we cannot confirm if the circuit can be turned on or off. It might imply that the circuit could be complete, but it is not clearly stated.

The correct answer is **C. A generator, a light bulb, and a closed switch**.
