1.	12. What is the difference between a direct curent and an altermating curmnaHow many times does AC used in India change direction in one second?
Answer» Indirect current(DC), the electric charge (current) only flows in one direction. Electric charge inalternating current(AC), on the other hand, changes direction periodically. Thevoltagein AC circuits also periodically reverses because thecurrentchanges direction.In India, as the frequency is 50Hz hence it changes The AC produced in India has a frequency of 50Hz.Coil is rotated at the rate of 50 revolutions per second. Since in one revolution of coil, the current reverses its direction 2 times , So in 50 revolutions of coil the current reverses its direction 2 x 50 = 100 Times. Thus AC supply in India reverses its direction 100 Times in one second.
