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.
