Answer1

The metallic strip fulfils the pathway of closing or opening the circuit of the torch whenever it is pushed forward it comes in contact with the metal collar at the base of the reflector and hence completes the circuit.

Answer 2

Electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.

Answer 3

The purpose of a switch in a series circuit is to make it easy to open or close the electrical circuit, turning the flow of electricity on or off. The purpose of the wires in a series circuit is to allow the electricity to flow from one device to the next. Wire is used to carry the flow of electrons.

Answer 4

Plastic or rubber is an insulator which does not allow electric current to pass through it. The handles of the tools like screwdrivers and pliers used by electricians for repair have covering of plastic or rubber so that electric current may not pass through these tools to the body of the electrician to harm him.

Answer 5

We should always dry our hands before touching an electric appliance because water is not pure and the dissolved impurities are good conductors of electricity.
