The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

If you measure a DC voltage, and want to get some idea of how “big” it is over time, it’s pretty easy: just take a number of measurements and take the average. If you’re interested in the average ...

In the consumer electronics world, knowing the difference between root mean square (RMS) and peak power ratings can make or break the performance and clarity of an audio system. In short, RMS power is ...

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 ...

Curious about how the square root of 2 relates to RMS voltage? ⚡🔢 In this video, we’ll break down why this mathematical concept is key to understanding how AC voltage is measured and calculated.

After using the DFB, the square root component is stunningly trivial in its application. Just plonk it on the schematic and configure it. Obviously its internals are far more complex and you can get ...

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 all know that electric utilities in the United States generate electricity at various 60-Hz voltage levels that result in a sine wave waveform. The height, or amplitude, of this sine wave is called ...
