Incandescent Light Bulb

An incandescent light bulb produces light by heating a thin filament, usually made of tungsten, until it glows. When electrical current passes through the filament, it heats up due to resistance, emitting visible light as a result. This process is relatively simple but inefficient, as much energy is lost as heat. Incandescent bulbs have been widely used for their warm, natural light but are being phased out in many areas due to their high energy consumption compared to newer lighting technologies like LEDs. They are known for their affordability and straightforward design, making them a common lighting choice for domestic use.
