Match the following: 1 Battery (a) Calculator 2 Human body (b) Very high melting point 3 Plastic (c) Collection of cells 4 Filament of a bulb (d) Conductors of electricity 5 Button cell (e) Insulator

1. Battery- Collection of cells. A battery is a collection of one or more cells whose chemical reactions allow the flow of electrons in the circuit. 2. Human body- Conductors of electricity. The human body is a conductor of electricity as it allows the flow of current through it. 3. Plastic- Insulator. Plastic is an insulator as it does not allow the flow of electricity through it. 4. Filament of bulb- Very high melting point. The filament of a bulb has a very high melting point and heats up once current passes through it. 5. Button cell- Calculator. A button cell is used in a calculator. A cell is a device used which converts chemical energy into electricity. 1 Battery (c) Collection of cells 2 Human body (d) Conductors of electricity 3 Plastic (e) Insulator 4 Filament of a bulb (b) Very high melting point 5 Button cell (a) Calculator

Match the following. Column A Column B 1 . Battery a. circuit 2 . Bell b. safety 3 . Geyser c. cells 4 . Switch d. heating coil 5 . Fuse e. electromagnetic

Battery - cells A battery is a combination of two or more than two cells. It is a source of electricity. Bell - electromagnetic A bell consists of an electromagnet for its working. When the switch is on the circuit inside the bell becomes a temporary magnet and the hammer attached to it strikes the gong. Geyser - heating coil Geyser is having a heating coil which works on the heating effect of the current. When a current is passed through it, it becomes hot and heats the water. Switch - circuit A switch is used to make or break an electric circuit. When the switch is in the 'ON' position, a current will flow in the circuit. Fuse - safety Fuse is a safety device in an electric circuit. It melts down whenever an excessive current flows through the circuit. Column A Column B 1 . Battery c. cells 2 . Bell e. electromagnetic 3 . Geyser d. heating coil 4 . Switch a. circuit 5 . Fuse b. safety
