A few months ago a personal computer trade magazine reviewed surge voltage protective power strips for home use. The article offered an explanation of what “120 volts RMS” power (what we typically ...

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 ...

This article was originally fairly superficial and frivolous, but has been expanded (a little) to explain the matter better. Amplifier power ratings are usually honest in Hi-Fi equipment, but become ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

So I'm finalising a set-up for my new build & I'd really like to get it right this time. I have an amplifier rated at RMS 330 watts (Max 600) x 1 channel at 4Ohms (from Sony) > The Amplifier will ...

When clients call you because operating problems on pieces of their 120V equipment cause them to suspect their facility's power supply, you have to decide where to start your investigation. Don't ...
