An electric bulb is a device which produces light when electricity is passed through its terminals. The bulb has two thick contact wires in the center with a thin wire attached between them. This thin wire is called filament. … A bulb is said to be fused if the filament gets broken.
What is electric bulb answer?
An electric bulb refers to an electric lamp which consists of a translucent or transparent glass housing. It is also known as a light bulb. This simple device has been used for the purpose of illumination for more than a century. Electric bulb refers to a device which produces light on the application of electricity.
What is called electric bulb?
electric-light bulb Add to list Share. Definitions of electric-light bulb. electric lamp consisting of a transparent or translucent glass housing containing a wire filament (usually tungsten) that emits light when heated by electricity. synonyms: bulb, electric light, incandescent lamp, light bulb, lightbulb.
What is the function of an electric bulb Class 6?
Function of an electric bulb is to produce light energy from the electricity passing through its filament. The filament gets heated up as the electricity passes through it.
What is a electric cell class 6?
An electric cell is a device which produces electricity capable to run smaller appliances like torch, clock, camera, radio etc. An electric cell has two terminals – positive (+) and negative (-). Positive side of an electric cell has a metal cap.
What is the purpose of using an electric bulb?
A light-bulb produces light from electricity. In addition to lighting a dark space, they can be used to show an electronic device is on, to direct traffic, for heat, and for many other purposes. Billions are in use, some even in outer space. Early people used candles and oil lamps for light.
Is used in electric bulb?
Filaments in incandescent light bulbs are made of tungsten. When electric current goes through the filament, the filament glows.
How many types of electric bulbs are there?
There are three basic kinds of light bulbs on the market: incandescent, halogen, and CFL (compact fluorescent light).
How does a bulb glow Class 6?
The electric circuit provides a complete path for electricity to pass (current to flow) between the two terminals of the electric cell. … When the terminals of the bulb are connected with that of the electric cell by wires, the current passes through the filament of the bulb. This makes the bulb glow.
What is the symbol for bulb?
A light bulb is shown as a circle with a cross inside it. It produces light when a current is passed through it.
What is a filament for Class 6?
Filament is usually made of very thin tungsten wire. It is the filament of the bulb which glows when electricity from cell is passed through it. (3) The two thick wires inside the glass bulb provides support to the filament and also make the connection of the filament to the outer circuit.
What are conductors for Class 6?
CBSE NCERT Notes Class 6 Physics Electricity and Circuits. Materials which allow electric current to pass through them are called conductors of electricity. Examples are iron nail, key, safety pin, water, human bodyetc.
Why do bulb has two terminals Class 6?
ANSWER ➡ The bulbs have two terminals because, a circuit can be completed only when there are both the positive terminal as well as negative terminal, as the current flow is allowed only when the circuit is complete. Hence, the bulb has two terminals.
What is a battery class 6?
Battery: When two or more cells are joined together, the combination is called a battery. Bulb: We get light from a thin tiny wire inside the glass cover. This is called filament. … The base of the bulb and the metal tip of the base are the two terminals of the bulb.
What is meant by battery Class 6?
A battery can be defined as an electrochemical device (consisting of one or more electrochemical cells) which can be charged with an electric current and discharged whenever required. Batteries are usually devices that are made up of multiple electrochemical cells that are connected to external inputs and outputs.
