Form Factor × Peak Factor =?

• A. Maximum Value/RMS Value
• B. Maximum Value/Average Value
• C. RMS Value/Average Value
• D. Average Value Maximum Value

Answer: (B)

Form factor: The ratio of r.m.s (or effective) value to average value is the form factor (Kf) of the Waveform. It has used in voltage generation and instrument correction factors.
Peak factor: The ratio of maximum value to the r.m.s value is the peak factor (Kp) of the waveform.
Form Factor × Peak Factor = (RMS Value / Average Value) * (Maximum Value / RMS Value) = Maximum Value / Average Value
