The rms value of a sine waveform is: A. the number of cycles completed in one second B. the time required to complete one full cycle C. equal to 0.707 times the peak amplitude D. equal to 1.41 times the peak amplitude E. None of the above

The correct answer is: C. equal to 0.707 times the peak amplitude.

The root mean square (rms)

Option A is incorrect because the number of cycles completed in one second is called the frequency.

Option B is incorrect because the time required to complete one full cycle is called the period.

Option D is incorrect because the peak amplitude is the maximum value of the sine wave.

Option E is incorrect because the rms value of a sine wave is not equal to 1.41 times the peak amplitude.
