A rectifier instrument reading a square wave of the same rms value as a sinusoid will read
Answer: B
Correct answer: high, because the square wave's form factor is smaller
A square wave has a form factor of 1.00, since its rectified mean equals its rms value. The instrument nonetheless multiplies the mean it measures by 1.11, so it reads about 11 per cent above the true rms. A waveform with a form factor above 1.11, such as a triangular wave, would be read low.
