Electricity is made at a power station and travels down large cables to people's houses. This electricity is known as mains power and is very dangerous. It can kill, so children should never play near it. Mains electricity is just a big circuit, so when you plug something in at home, you complete the circuit from your house to the power station and back again. Power stations are like a battery and provide the push. They make electricity by burning fuels such as coal or gas.
