Identifying the Different Parts
A light bulb is a simple device that converts electrical energy into light. It consists of several key components:
1. Base: The base is the threaded or bayonet part of the bulb that screws into the socket. It provides electrical contact between the bulb and the power source.
2. Shell: The shell is the glass or plastic enclosure that surrounds the other components of the bulb. It protects the internal parts from damage and helps to diffuse the light.
3. Filament: The filament is a thin wire made of tungsten or another high-resistance material. When electricity flows through the filament, it heats up and glows, producing light.
4. Support wires: The support wires hold the filament in place and ensure that it does not sag or break.
5. **Lead wires**: Two lead wires connect the filament to the base of the bulb, allowing electricity to flow through it. Lead wires are typically made of copper or aluminum and are covered in an insulating material. They are attached to the base of the bulb by solder or other metal connectors. The lead wires are essential for allowing the filament to receive electrical current and produce light. The color coding of the lead wires may vary depending on the type of light bulb:
| Lead wire color | Connection |
|---|---|
| Black or brown | Hot (positive terminal) |
| White or gray | Neutral (negative terminal) |
| Green or bare copper | Ground (safety ground) |
