Answer the following in 5-6 sentences:
1. Describe the working of an electric bulb with a neat labeled diagram
Answers
Answer:
Light bulbs have a very simple structure. At the base, they have two metal contacts, which connect to the ends of an electrical circuit. The metal contacts are attached to two stiff wires, which are attached to a thin metal filament. The filament sits in the middle of the bulb, held up by a glass mount. The wires and the filament are housed in a glass bulb, which is filled with an inert gas, such as argon.
Explanation:
Electric bulb is also known as the incandescent light bulb is an electrical appliance which provides light. When a wire filament inside the bulb is heated, it starts glowing hence emitting light rays. The bulb was invented by Thomas Edison.
Tungsten is most commonly used to make the filament as it is able to withstand high levels of heat.
A glass enclosure surrounds the filament to prevent oxidation.
The inner cavity of the bulb is filled with an inert gas like neon or xenon.
The filament is attached to terminals which supply electric current to generate heat...
