To wire five small light bulbs, follow these steps:

1. Gather the necessary materials: a power source, a switch, a junction box, electrical wire, and the light bulbs.

2. Connect the power source to the switch using a black wire (hot wire).

3. Connect the switch to the junction box using a white wire (neutral wire).

4. Connect the junction box to the light bulbs using a red wire (hot wire) and a black wire (hot wire).

5. Connect the light bulbs to each other in series, using the red and black wires.

6. Secure all connections with wire nuts and cover the junction box with a cover.

Wiring five small light bulbs in series is a common method due to its simplicity and cost-effectiveness. When bulbs are wired in series, the voltage is divided among them, which can be beneficial if the bulbs require a lower voltage to operate efficiently. According to the National Electrical Code (NEC), wiring in series is acceptable for low-voltage applications, such as 12V or 24V systems, where the total voltage does not exceed the rated voltage of the bulbs. This method also ensures that if one bulb burns out, the others will remain lit, as the circuit is not broken. Additionally, wiring in series can be more energy-efficient, as it reduces the overall current draw compared to wiring them in parallel.
