How to Convert AC to DC: 11 Steps (with Pictures) - wikiHow
2. Divide the AC voltage by the square root of 2 to find the DC voltage. Since an AC power supply sends voltage in alternating waves, DC voltage will be lower once you convert it. Write out the formula V AC /√ (2) and replace V AC with the AC voltage you found with your multimeter.
Alternating Current - Definition, Working Principle, AC ...
An alternating current has a wide advantage over DC as AC is able to transmit power over large distances without great loss of energy. AC is used mostly in homes and offices mainly because the generating and transporting of AC across long distances is a lot easier. Meanwhile, AC can be converted to and from high voltages easily using transformers.

Induction Motor Working Principle – StudiousGuy
As the alternating current flows through the stator windings, it produces a magnetic field around the coils of the windings. The coils inside the stator are arranged in such a manner (120° apart spatially) that the magnetic field produced by them starts to rotate as a consequence of the periodically reversed direction of input AC.
