Describe the structure of torch and explain its working.
Answers
Answer:
Torch consists of a hollow cylindrical barrel in which cells (Battery) are fitted. At one end of it there is a lid with screw which can be opened and closed. When the lid is closed and the switch is ON, the circuit is completed. When the circuit is closed then the current starts to flow in the circuit
Answer:
Cell
A cell is a device used to power electrical circuits. It has two terminals; positive and negative. The terminal marked negative is the source of electrons, that when connected to a circuit delivers energy.
Switch
A switch is a device that can break an electrical circuit by diverting the current from one conductor to another conductor or an insulator. These set of contacts are termed as open and closed. Open circuit means that the contacts are separated and the circuit is broken, so no current is flowing.
Light Bulb
A light bulb is a device that produces light from electricity. Light bulbs turn the electricity to light by sending current through a thin wire called filament.
