The input transformer is likely to be the most expensive part of the entire project. As an alternative, a couple of 12 Volt car batteries could be used. The input voltage to the regulator must be at ...

Normally when we hear of a Champ guitar amp, we think of a sweet-sounding rig that puts out 6 Watts through an 8-inch speaker. [John Chambers] of Champ Electronics wanted to build a true champion for ...

What's the difference between amperes and watts, and what does voltage have to do with them? Here's how you can tell which ...

The Voltec powetrain used in the 2011 Chevrolet Volt has never been meant for just the one vehicle. Restricting a new technology developed at great expense to a single niche vehicle makes poor ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

A lot of the analog-circuit conversation these days is centered on low-power and thus low-voltage considerations. That makes sense for operational amplifiers (op amps), of course, since these basic ...

Scans, programming, and ADAS calibrations require stable, high-capacity battery support to prevent voltage drops and ...
