What is the period of 60 Hz electrical power?

Short Answer

Expert verified

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

Step by step solution

01

Identification of the given data

The frequency of electric power is, f = 60 Hz

02

Definition of frequency

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.

03

Determination of time period

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.
