Alternating current (AC)
Alternating current (AC) is electric current that regularly reverses its direction of flow. Produced by AC generators, AC is used in most homes and businesses (see Electric generator). By contrast, direct current (DC) does not alternate. It always flows in the same direction and is produced by batteries and DC generators.

Electric generator
Electric generator is a machine that changes mechanical energy—the energy of motion—into electrical energy. Generators produce almost all the electric power used by people. They furnish electric power that runs machines in factories, provides lighting, and operates home appliances. Generators were once called dynamos, a shortened form of the term dynamoelectric.
Lenz's Law
Lenz's law is a principle that relates magnetism to electric current, describing the direction of a current produced by a changing magnetic field.

Henry Joseph
Henry, Joseph (1797-1878), an American physicist, became famous for his discoveries in electromagnetism. He anticipated both Samuel F. B. Morse's invention of the telegraph and Michael Faraday's discovery of electromagnetic induction. Henry received no credit for his work at the time, but the unit of electrical inductance is now called the henry (see Henry).
