Homework Help: RMS question

  1. May 10, 2013 #1
    1. An oscilloscope is used to measure the voltage across
    two components using Channel A and Channel B. Deduce the RMS voltage of the signal measured by
    Channel A

    I just want to know what they mean by "deduce the RMS voltage"

    Do i need to calculate the Vrms?

    Based on the readings that you can get from the oscilloscope, you should either be able to get Vrms directly or Vmax to get Vrms.

    It sounds like it, assuming it's a sine wave take your amplitude and divide it by the square root of 2.
