Question

What Is meant by ac of 220 V and 50Hz? How many times direction of current Changes in 1sec in this case?

Answer 1

Answer:The voltage supplied to the circuit is 220v and 50 times per 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.
