What is alternating current electricity?

Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current"Effects at high frequencies · Mathematics of AC voltages · Information transmission

Transformers · DC stands for “Direct Current,” meaning voltage or current that maintains constant polarity or direction, respectively, over time. · AC stands for “

Alternating current (AC) is the type of electric current generated by the vast majority of power plants and used by most power distribution

All electric currents lose power when they flow for long distances, but AC circuits lose much less power than DC circuits. The electrons in an AC circuit don't
