Electricity and Circuits class 6
We use electricity for many purposes to make our tasks easier. For example, we use electricity to operate pumps that lift water from wells or from ground level to the rooftop tank.
Electricity to the bulb in a torch is provided by the electric cell. Electric cells are also used in alarm clocks, wristwatches, transistor radios, cameras and many other devices.
The metal cap is the positive terminal of the electric cell. The metal disc is the negative terminal. All electric cells have two terminals; a positive terminal and a negative terminal. An electric cell produces electricity from the chemicals stored inside it. When the chemicals in the electric cell are used up, the electric cell stops producing electricity. The electric cell then has to be replaced with a new one.
The thin wire that gives off light is called the filament of the bulb. The filament is fixed to two thicker wires, which also provide support to it.
Sometimes an electric bulb does not glow even if it is connected to the cell. This may happen if the bulb has fused. An electric bulb may fuse due to many reasons. One reason for a bulb to fuse is a break in its filament. A break in the filament of an electric bulb means a break in the path of the current between the terminals of the electric cell. Therefore, a fused bulb does not light up as no current passes through its filament.
Materials that allow the electric current to pass through them are conductors of electricity Insulators do not allow an electric current to pass through them
