The RMS value of a time dependent voltage or current is based on the simple concept of equality of power dissipation; however, its theoretical calculation or instrument implementation may not be easy.

We had a requirement to measure the RMS value of a unipolar square wave being fed to a resistive load. Our resistive loads were light bulb filaments (Numitrons) so the degree of brightness was ...

How many times have you poked around a circuit with a digital multimeter (DMM), read an AC voltage value, then gone on your merry way? Ever wonder if your meter is giving you peak value, average value ...
