What is the frequency of the current if the period of alternating current oscillations is 0.02 s?
| June 15, 2021 | education
AC frequency is the number of complete cycles of EMF change that occurred in 1 second.
For calculation, we apply the formula
f = 1 / T,
Where
f – current frequency Hertz (Hz);
T – period in seconds (s).
Substitute the values and calculate
f = 1 / 0.02 = 50 Hz.
Answer: the frequency of the current is 50 Hz.
