Electricity
Lightning is the most visible way we see electricity in nature. Electricity is a type of energy found in nature. We see it in nature when we see a lightning flash or when we stroke an animal and feel sparks.

Scientists have also found we can make electricity if we pass a magnet close to a metal wire or if we put the right chemicals in a jar with two different kinds of metal rod.

Scientists have observed that electricity seems to flow like water from one place to another, either as a spark or as a current in a metal. They now know that all matter has electric charge but this is mostly cancelled out by the presence of matter with an opposite charge. We only see an effect when there is too much or too little electric charge in one place so that it is not cancelled out.

Since the nineteenth century, electricity has been made into a useful creation that affects every part of our lives. Until then it was just a curiosity or a force of nature seen in a thunderstorm.

To be useful electricity has to be made from other sources of energy such as by burning coal or oil or from wind or flowing water in a power station.

Electricity arrives at our homes through wires from the places where it is made. It is used by Electric Lamps for producing light, Electric Heaters to produce heat etc. It is also used by many devices like washing machines, Electric Cookers, etc for doing work. In factories, electricity is used for running machines and computers.

The people who deal with electricity and electrical devices in our homes and factories are called "Electricians
hhahaha like me and u....
