A decade or so ago, I designed a simple circuit that included a quad optoisolator arranged in a full-wave analog-multiplier bridge (Figure 1). It sensed and calculated watts of ac-power consumption ...

Batteries can be connected in series, parallel, or a combination of both, in order to give different power characteristics to ...

The time is upon us:The electric cars cometh. It's inexorable, so like it or lump it, it's time to figure them out. First, though, we need to understand a few terms and the basic concepts behind those ...

I'd like to monitor the amount of power (in watts) going into my speakers. I'm not concerned about over driving them or anything, I'm just curious how much power I'm actually using. I connected a volt ...
