The form factor is the ratio of_______?
Correct answer: B. r.m.s. value to average value
- A. peak value to r.m.s. value
- B. r.m.s. value to average value
- C. average value to r.m.s. value
- D. none of the above
Explanation
For an alternating waveform, form factor is defined as the ratio of its r.m.s. value to its average value, usually the rectified average. For a sine wave, this ratio is about 1.11.
