3. Electrical fundamentals

A sine wave has 5 amps RMS value. What is the peak value?

  • 7.07 amps.
  • 6.37 amps.
  • 10 amps.

Explanation from PART66Online

For a sine wave the peak equals RMS * sqrt 2 = 5 * 1.414 = 7.07 A. The value 6.37 A corresponds to 0.637*something (the average-related factor) and 10 A would only arise from doubling, so neither fits the RMS-to-peak conversion.

Hey!
You must multiply RMS value by 1.414 to get peak value.
