Question

explain the working of an electric torch with the help of a labelled diagram

Answer 1

A torch is a practical example of a simple electric circuit. It is an electric device that emits light. It consists of a bulb, electric cells, a switch, a reflector, and a cylindrical shape casing.

Function of each component of a torch

Bulb: The bulb emits light when electric current flows through its filament.


Electric cell: The cell is an electricity-producing device. The required current for the filament of the bulb is supplied by it.


Switch: The switch is used to complete and break the circuit inside the torch. In simple words, it is used to turn the torch on and off.


Reflector: The reflector is a curved, silvered mirror. It is used to focus the light in a particular direction.



Casing: The casing is used to provide covering for the basic components of the torch for protection and safe handling.

Answer 2

A torch is an example of a basic electric circuit in action. It's a light-emitting electronic gadget.

Explanation:

A bulb, electric cells, a switch, a reflector, and a cylindrical form enclosure make up the device.

Each component of a torch has a specific function.

When electric current travels through the filament of a bulb, it produces light.

An electric cell is a device that generates electricity. It provides the needed current for the filament of the bulb.

The switch within the torch is used to complete and break the circuit. To put it another way, it is utilised to turn on and off the torch.

A curved, silvered mirror serves as the reflector. It is used to guide light in a certain direction.
