What is the RMS voltage of a sine wave with a value of 17 volts peak?

  1. 8.5 volts
  2. 12 voltsRespuesta correcta
  3. 24 volts
  4. 34 volts

Explicación

RMS is the peak value divided by the square root of two: 17 / 1.414 = 12.0 volts. The 8.5-volt distractor is simply half the peak, which is not the RMS relationship.
