Does your DMM give you accurate readings? Unless you're using a True RMS meter, probably not. Switching power supplies and other sources of waveform distortion are everywhere. An average-responding ...

If you make electrical measurements, you probably use a handheld digital multimeter (DMM). With dozens of handheld DMMs on the market, how can you decide which one is right for you? To give you a feel ...

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.

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.
