Question
What is the period of the commercial ac power system voltage in NorthAmerica?
Solution
The frequency of the commercial AC power system in North America is 60 Hz. The period of a wave is the reciprocal of the frequency. Therefore, to find the period (T), you use the formula:
T = 1/f
Substituting the given frequency:
T = 1/60
This gives a period of approximately 0.0167 seconds, or 16.7 milliseconds.
