Question

Which list of components creates a circuit through which an electric current can flow? (1 point)

a generator, a light bulb, and a closed switch

Oa generator, two light bulbs, and an open switch

Oa battery, insulated wires, a buzzer, and an open switch

a battery, Insulated wires, and a buzzer

Answer 1

To create a complete circuit through which an electric current can flow, you need a source of electricity (like a battery or generator), a load (like a light bulb or buzzer), and a complete path for the current to flow (closed switch or connected wires).

Looking at your options:

1. **a generator, a light bulb, and a closed switch** - This option creates a complete circuit.
2. **a generator, two light bulbs, and an open switch** - This option does not work because the switch is open, preventing current flow.
3. **a battery, insulated wires, a buzzer, and an open switch** - This option does not work because the switch is open, preventing current flow.
4. **a battery, insulated wires, and a buzzer** - This option could potentially work if the circuit is completed (for instance, if the buzzer has a built-in switch), but without a switch, the circuit may remain open depending on the specific setup.

Thus, the best answer here is **a generator, a light bulb, and a closed switch**.
