The electricity that we get from power outlets and batteries can power all different kinds of devices. The fact is that electricity can be used in a thousand different ways. For example:
Electric motors turn electricity into motion.
Light bulbs, fluorescent lamps and LEDs turn electricity into light.
Computers turn electricity into information.
Telephones turn electricity into communication.
TVs turn electricity into moving pictures.
Speakers turn electricity into sound waves.
Stun guns turn electricity into pain.
Toasters, hair dryers and space heaters turn electricity into heat.
Radios turn electricity into electromagnetic waves that can travel millions of miles.
X-ray machines turn electricity into X-rays.

­It is hard to imagine modern people living without electricity.
