For the same peak value which of the following wave will 'have the highest r.m.s. value?
Correct answer: A. square wave
- A. square wave
- B. half wave rectified sine wave
- C. triangular wave
- D. sine wave
Explanation
For the same peak value, a square wave remains at its peak magnitude throughout the cycle, so its RMS value equals the peak value. A sine, triangular wave, and half-wave rectified sine have smaller RMS values.
