What are the two terminals of electric bulb?

The base of the electric bulb and the metal tip of the base are the two terminals of the bulb. One is called a positive terminal while the other is called a negative terminal. The filament of the electric bulb is connected to its terminals.

Why there are two terminals in electric bulb?

Electricity and Circuits

The bulbs have two terminals because, a circuit can be completed only when there are both the positive terminal as well as the negative terminal, as the current flow is allowed only when the circuit is complete. Hence, the bulb has two terminals.

What are the two terminals of electricity?

An electric cell has two terminals, one positive and one negative because of which the current cannot pass through one side. It can only travel through opposite sides. The positive terminal in an electric cell is known as cathodes and that of the negative terminal is called anode.

What is a bulb Class 6?

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 the fused bulb?

When electricity is passed through the terminals of the bulb, the filament gets heated up and produces light. It is said that a bulb is fused if the filament is broken. When the filament of the bulb gets broken, then no electric current will pass through it and the bulb is said to be fused.

Where are the two terminals of an electric cell located?

12.1 ELECTRIC CELL. metal cap is the positive terminal of the electric cell. The metal disc is the negative terminal.

How are the terminals of an electric bulb different from those of an electric cell?

An electric cell has two terminals; one is called positive (+ ve) while the other is negative (– ve). An electric bulb has a filament that is connected to its terminals. An electric bulb glows when electric current passes through it.

Which of the following has two terminals?

Two terminals: An electric cell has two terminals, a negative terminal and a positive terminal (as shown in the given figure).

What is the wire inside an electric bulb called?

The thin wire present inside the light bulb is named as the filament of the bulb. It is made of tungsten.

Which electric cell has terminals?

An electric cell has two terminals ; one is called positive (+ ve) while the other is negative (– ve). An electric bulb has a filament that is connected to its terminals . An electric bulb glows when electric current passes through it.

How many terminals are in an electric cell?

All electrochemical cells have two terminals, referred to as the anode and cathode or positive (+) and negative (-).

What is meant by electric bulb?

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 structure of bulb?

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 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.
