what is meant by 60Hz AC current?

Question

I have to answer this question on my HVAC test and I don't recall reading about it and I can't find it in the book.

Answer 1

Hz is frequency (cycles per second)

AC is alternating current.

The polarity reverses sixty times per second.

Answer 2

It is turning cycle of an electric generator per second.

f=60 1 /sec = 60 Hertz = 60 sec^(-1)



When we produce an alternative current by a generator it turns around itself.This number of cycle is fixed 60 Hz.

Answer 3

The frequency at the polarity changes(+and -) is 60 cycles / sec.
