The formula to calculate the frequency (f) of an AC (Alternating Current) waveform is:
=
1
f=
T
1
Where:
f represents the frequency of the AC waveform in Hertz (Hz).
T is the period of the waveform in seconds (s).
The period (
T) is the time it takes for one complete cycle of the AC waveform to occur. It is measured in seconds. The frequency (
f) is the number of complete cycles that occur in one second and is measured in Hertz.
Conversely, you can calculate the period from the frequency using the formula:
=
1
T=
f
1
Keep in mind that AC waveforms can have various shapes, such as sine waves, square waves, triangle waves, and more. The formula for calculating frequency remains the same regardless of the waveform shape, as long as the waveform is periodic.
