Electricity: The Invisible Force That Powers Our World

Electricity is a type of energy that makes things work. It is all around us, but we can't see it. We can only see the effects of electricity, such as when a light bulb turns on or a fan starts spinning.

Electricity is created by the movement of tiny particles called electrons. Electrons are negatively charged particles that orbit the nucleus of an atom. When electrons are freed from their atoms, they can flow through a conductor, such as a metal wire. This flow of electrons is what we call electric current.

Electricity is used in many different ways in our homes and schools. It powers our lights, appliances, and computers. Electricity is also used in transportation, medicine, and many other fields.

So how is electricity generated?Β 
Fossil fuels
Coal, oil, and natural gas are fossil fuels that can be burned to generate electricity.

Nuclear energy
Nuclear energy is generated by splitting atoms of uranium.

Renewable energy sources
Renewable energy sources such as solar, wind, and hydroelectric power can also be used to generate electricity.

Electricity is a powerful and versatile form of energy. It is essential to our modern way of life.
