(d) In India, the AC changes direction after every 50 second​

Answer 1

Answer:

d)In India, the AC changes direction after every 50 second

Explanation:

50 Hertz (Hz) means the rotor of the generator turns 50 cycles per second, the current changes 50 times per second back and forth, direction changes 100 times. That means the voltage changes from positive to negative, and from negative to positive voltage, this process converts 50 times/second.
