Explain the structure of a bulb
Answers
☆ Structure Of An Electric Bulb ☆
The electric bulb is a device that runs on electricity. It gives light when a suitable material inside it gets heated to a high temperature. This suitable material is a thin wire called the filament. It is made of metal. The filament heats up when an electric current passes through. It heads up so much that it begins to flow and emits light.
The filament is connected to two speaker wires that are the supporting wires. They provide support to the filament. One of these wire is connected to the metal case at the base of the bulb. The other thick wire is connected to the metal tip at the centre of the base and the metal casing at its lower end act as terminals of the bulb. These two terminals do not touch each other. The outer case of the bulb is made of glass and is fixed to a metallic base.
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.
