Question

In A.C supply number of cycles per second is called

Answer 1

The number of cycles per second in AC power supply are known as Oscillations.

The Alternating Current (AC) supply in India and countries like the United Kingdom have Frequency of 50 Hz, while in countries like the United States, it is 60 Hz.

This means that the AC voltage oscillates at a rate of 50 or 60 complete cycles every second i.e. it completes the forward - backward movement, 50 to 60 times.

The unit of Hertz is named after the German physicist, Heinrich Hertz. He discovered and proved the existence and transmission of electric oscillations.
