Car batteries often appear to fail without warning because the early stages of deterioration do not produce symptoms that ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how ...

Combining Cor Van Rij's JFET test socket with two DMMs, a current limiter, switches and a wall wart yield a simple, accurate ...

Discover the best home-improvement products—lab-tested, expert-approved upgrades for kitchens, baths, and beyond from Good ...

Abstract: Elevated temperature is the main cause of electronic circuits failures, thus a proper thermal management is indispensable. The heat from operating circuits is dissipated by conduction, ...

Abstract: This article concerns passive magnetic energy harvesters (PMEHs) employed to supply low-voltage (typically dc) loads from high-ac-current-carrying conductors (e.g., a drone battery charging ...

When three resistors are connected in series to a battery, they form a simple yet fundamental circuit that demonstrates key ...
