Determine the frequency of the periodic waveform shown here Correct Answer 10 Hz

Concept:

  • The angle between zero points of AC quantities is called as phase difference.
  • Time period is the time taken to complete one cycle of periodic waveform.
  • Frequency is the reciprocal of time period.
    • f = frequency = 1/T

In the figure shown,

ϕ = phase difference

A = amplitude

T = time period

Application:

Given that, the time period of the periodic waveform shown in the question is 100 m-sec

∴ T = 100 x 10-3

So, the frequency of the periodic waveform is

f = 1 /T

f = 1 / (100 x 10-3)

f = 10 Hz
