#94: RMS Voltage for Sine and square waves, and why your DMM might not work right!
This video discusses the meaning of RMS voltage, and runs through an example of sine waves illustrating the 0.707 "factor". Examples of AC square waves and digital PWM waves are also shown, along with cautions regarding the results obtained with DMMs, including True-RMS DMMs, which may not read the RMS values of digital waveforms correctly. Notes from the video can be found here:
