Electric torch is an electronic device which is used to artificially produce light .

The working procedure of an electric torch is :

1) When we click the "ON" switch of the torch then the electricity flows from the battery chamber to the terminals of the bulb which is connected with that torch.

2) When the bulb gets enough amount of electricity ,the filament or the diode part of that bulb ,starts glowing and produces light.

The mechanics of a torch seem so easy that’s it’s often overlooked. Here’s a step-by-step explanation of how your everyday battery powered torch works:

1 – This part of the torch is called a case. It is the tube that encompasses the parts of the torch.

2 – This part of the torch is the contact throughout the torch. It is a very thin spring or strip of metal that runs through the torch, electronically connecting the various parts of the torch. This parts conduct electricity and completing the circuit.

3 – This is the switch of the torch. The flow of electricity is activated when you switch the torch on, turning the light on. The flow of electricity is interrupted when the switch is turned off, turning off the light.

4 – This part of the torch is called a reflector. It’s the plastic part, coated with a shiny aluminum layer that sits around the lamp and transmits the light rays from the lamp to allow a steady light beam.

5 – This part of the torch is called the lamp. It is known as the light source in a torch. In most torches, the lamp is either an incandescent bulb or a solid-state bulb, also known as an LED.

6 – This part of the torch is known as the lens. It is the clear, plastic part you see on the front of the torch that protects the lamp, since the lamp is made of glass and may easily be broken.

7 – This part of the torch is where batteries are inserted. When activated correctly, the batteries are the power source for your torch.
