HOW DOES ELECTRICITY WORK
Electricity for your house comes from a big power station where there is a huge piece of machinery called a generator. Inside the generator is an electromagnet, which is an iron core with wires which coil around it but do not touch it. In a circle around the magnet— also not touching it—there are other coils of wire.
Power, usually from steam or falling water, makes the electro magnet whirl rapidly inside the coil. And this produces electricity, electric current in the outer circle of wire.
The electric current flows from the generator into cables that run sometimes underground and sometimes high up on poles.
They carry the current everywhere it is needed. A cable brings it into your house.
When you flip a light switch or turn on your television set, you bring the electric current into your room.
