Question

meaning of frequency of an alternating current

Answer 1

For an oscillating or varying current, frequency is the number of complete cycles per second in alternating current direction. The standard unit of frequency is the hertz, abbreviated Hz.

Answer 2

If the current reverses its direction in equal intervals of time, then that current is called alternating current or AC.

The number of revolutions completed in one second in alternating current direction is called AC frequency.
