How do you find the rms voltage displayed on an oscilloscope screen?
Homework Answers
we will get the peak or average voltage from the oscilloscope
divide that value by 
Scopes show the instantaneous value of the voltage vs. time. RMS, peak, average, and pk-pk are all ways of expressing the overall value of the waveform, but only the scope shows the instantaneous values. You can usually calculate those values from the scope display.
