The square waveform of current has following relation between r.m.s. value and average value?
Correct answer: A. r.m.s. value is equal to average value
- A. r.m.s. value is equal to average value
- B. r.m.s. value of current is greater than average value
- C. r.m.s. value of current is less than average value
- D. none of the above
Explanation
A square wave has constant magnitude during each interval, so its RMS magnitude and average rectified magnitude are equal. This assumes the usual engineering meaning of average value as the average magnitude, not the signed average of a symmetrical bipolar wave.
