**What is the period of 60 Hz electrical power?**

The time period of 60 Hz electrical power is 0.017 s.

The frequency of electric power is, f = 60 Hz

**Any particular event that occurs at a specific rate for a defined period of time is termed frequency. It can be determined by taking the inverse of the time period and it is measured in terms of Hertz.**

Write the expression for the time period.

\(T = \frac{1}{f}\)

Here, f is the frequency of electric power.

Substitute all the values in the above expression.

\(\begin{array}{c}T = \frac{1}{{60\;{\rm{Hz}}}} \times \frac{{1\;{\rm{Hz}}}}{{{{\rm{s}}^{ - 1}}}}\\ = \frac{1}{{60\;{{\rm{s}}^{ - 1}}}}\\ = 0.017\;{\rm{s}}\end{array}\)

Thus, the time period is 0.017 s.
