In India, it is 50hz that is it changes its extremity 50 times in a second… .
Rotating current (AC) streams a fraction of the time one way and a fraction of the time in the other, changing its extremity 100 - 120 times each second.
Recurrence of AC current in India and UK is 50hz where as in Us it's 60hz.
