ALTERNATING CURRENT

Alternating current (AC) is an electric current which periodically reverses

direction, in contrast to direct current (DC) which flows only in one direction.

Alternating current is the form in which electric power is delivered to businesses

and residences, and it is the form of electrical energy that consumers typically use

when they plug kitchen appliances, televisions and electric lamps into a wall

socket. A common source of DC power is a battery cell in a flashlight. The

abbreviations AC and DC are often used to mean simply alternating and direct, as

when they modify current or voltage.

Тhe number of cycles per second is the frequency of an alternating current.

Тhere are two frequencies: the standard for Europe is 50 cycles per second while

the standard for the USA is 60 cycles per second. А standard frequency has а great

advantage since different systems сan bе interconnected.
