In India, the frequency of Alternating Current (AC) supply is
Answer: A
The AC supply in India is at 50 cycles per second (50 Hz).
India's grid, like that of most of Europe, Asia and Africa, runs at 50 Hz with a domestic voltage of 220-230 V.
60 Hz is used in the Americas and parts of Japan and some other countries. 100 and 120 cycles per second are double those values, the ripple frequency of rectified AC, not the supply frequency.
