Introduction:
An electric bulb, also known as an incandescent light bulb, is a device that produces light when an electric current passes through a filament, heating it to a high temperature until it glows. This innovation by Thomas Edison revolutionized the way we illuminate our homes, workplaces, and streets. In this article, we will delve into the definition of an electric bulb, its history, how it works, and its different types, providing readers with a comprehensive understanding of this essential tool in our daily lives.

History of the Electric Bulb:
The invention of the electric bulb dates back to the 19th century when inventors like Thomas Edison, Joseph Swan, and Humphry Davy made significant contributions to its development. Thomas Edison is widely credited with the successful commercialization of the incandescent light bulb in 1879, using a carbonized bamboo filament that could last for hours. This marked the beginning of a new era in lighting technology, paving the way for further advancements in the field.

How Does an Electric Bulb Work?
An electric bulb operates on the principle of incandescence, where electricity flows through a thin wire filament inside the bulb, heating it up to temperatures around 2,700 degrees Celsius. As the filament heats up, it emits visible light and a small amount of heat. The bulb is filled with an inert gas like argon to prevent the filament from oxidizing and burning out quickly. The electric current is controlled by a wire or tungsten filament, which determines the brightness and color of the light produced.

Types of Electric Bulbs:
There are several types of electric bulbs available in the market today, each with its own unique characteristics and applications. Incandescent bulbs, though being phased out in many countries due to their low energy efficiency, are still widely used for their warm light quality. Compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs) have gained popularity in recent years for their energy-saving benefits and long lifespan. Halogen bulbs are another option known for their bright, white light and precise beam control, making them ideal for task lighting.

Conclusion:
In conclusion, the electric bulb has come a long way since its inception, evolving from the carbonized filament models of the past to the energy-efficient LED bulbs of today. Understanding the definition, history, working principle, and types of electric bulbs is crucial for making informed decisions when choosing lighting solutions for different settings. As technology continues to advance, we can expect further innovations in lighting that are both sustainable and effective.
