How Does Electricity Work

HOW DOES ELECTRICITY WORK?

ELECTRICITY FROM 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 coils of wire.

POWER, USUALLY FROM STEAM OR FALLING WATER, makes the magnet whirl rapidly inside the current. And this produces electicity, electic current in the outer circle of the 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 the television set,

YOU BRING THE ELECTRIC CURRENT INTO YOUR ROOM.
