Although not really a cost-effective or a required skill unless you have some very specific needs not met by off-the-shelf power resistor options, making your own own wirewound power resistor is ...

An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of ...

I need an adjustable power resistor that can be switched with a resolution of 1Ω. After some thought and web surfing, I bought some 10W wirewounds, which are available in E24 values so that 1, 3, 12 ...

Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...
