FAQs on How does an Electric Bulb Work?, Electricity and Circuits, Class 6 Science Video Lecture

1. How does an electric bulb work?
Ans. An electric bulb works by converting electrical energy into light energy. Inside the bulb, there is a filament made of tungsten wire. When an electric current passes through the filament, it heats up and starts glowing, producing light.
2. What is the role of electricity in circuits?
Ans. Electricity plays a crucial role in circuits by providing the flow of electric current. It powers various electronic devices and allows the transfer of energy from one component to another within a circuit.
3. What are the main components of an electric bulb?
Ans. The main components of an electric bulb are the filament, the glass bulb, and the base. The filament is the part that produces light when heated, while the glass bulb protects the filament and allows the light to pass through. The base of the bulb provides the electrical connections.
4. How does the filament in an electric bulb produce light?
Ans. The filament in an electric bulb produces light through a process called incandescence. When an electric current passes through the filament, it heats up to a very high temperature, causing it to emit light. The filament glows due to the high temperature.
5. Can an electric bulb work without electricity?
Ans. No, an electric bulb cannot work without electricity. Since the bulb requires an electric current to flow through the filament and produce light, it is essential to have a source of electricity to power the bulb.
