1) The metallic strip in the torches is used to make electrical connection between all the parts of the torch. The parts are the batteries, the bulb, switch. The metallic strip conducts electricity and maintains the electrical connection.
3) Electrical circuit is a connection of electrical components, that is, switch, bulb, wires, ammeter and many more.
4) Electrical switch is used to make the electrical circuit closed or open, allowing the current to pass or not.
6) We should dry our hands to prevent ourselves from the risk of getting an electrical shock, because water conducts electricity because it is not pure and has impurities.
7) Working of an electrical torch -:
• As soon as we press the switch of a torch, electricity starts flowing in the metallic strip that connects all the other parts of the bulb. This is due to the chemical present in the batteries.
• Flow of electricity heats up the filament.
• And the bulb lights up.
