Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, 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 … See more
Electrical energy is distributed as alternating current because AC voltage may be increased or decreased with a transformer. This allows the power to be transmitted through power lines efficiently at high voltage, … See more
A direct current flows uniformly throughout the cross-section of a homogeneous electrically conducting wire. An alternating current of any … See more
Alternating current is used to transmit information, as in the cases of telephone and cable television. Information signals are carried over a … See more
The frequency of the electrical system varies by country and sometimes within a country; most electric power is generated at either 50 or 60 See more
The first alternator to produce alternating current was an electric generator based on Michael Faraday's principles constructed by the French instrument maker Hippolyte Pixii in … See more

Synchronization (alternating current) - Wikipedia
In an alternating current (AC) electric power system, synchronization is the process of matching the frequency, phase and voltage of a generator or other source to an electrical grid in order to transfer power. If two unconnected segments of a grid are to be connected to each other, they cannot safely exchange AC power until they are synchronized.
