Power resistors, rheostats (variable resistors), and other electrical loads are useful for testing power supplies and regulators. Though functionally equivalent to a mechanical rheostat, electronic ...

Inspired by jellyfish, researchers have created an electronic skin that is transparent, stretchable, touch-sensitive, and repairs itself in both wet and dry conditions. The novel material has ...

While almost always called "potentiometers" (which are technically defined as three-terminal variable voltage dividers), many "pots" actually end up being used as variable resistors (rheostats) ...

This Application Note illustrates the power dissipation and thermal transfer through the semiconductor package using thermal resistance model, which is critical in considering thermal management to ...

Download this article in PDF format. Proper wiring and probing/contacting are critical to making successful measurements. When testing cells or batteries, using good engineering practices is important ...

"Ab wheels" are widely used to build core strength, with some models offering a limited amount of resistance via spring mechanisms or elastic bands. The ZeroWheel takes things further, however, by ...

Ningbo Joyson Electronic has been granted a patent for a programmable resistance circuit that configures selected resistances using a reference resistor. The circuit utilizes a modulated voltage ...

The material, developed by researchers from the National University of Singapore (NUS) and and the University of California, Riverside in the US, can self-heal in aquatic environments just like a ...
