The Easy Way to Calculate ResistanceWhether you’re building your first Arduino project, repairing a vintage amplifier, or ...

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 ...

Resistor: A passive chunk of material that resists the flow of electrical current. A terminal is connected to each end you’re done. What could be simpler? It turns out it’s not so simple at all.

Messing around with Arduino can lead to some fun projects — like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...

What kinds of applications utilize precision resistor trimming? Obvious applications include setting operational-amplifier gain and offset and voltage regulator output (Fig. 1a and 1b). But there are ...

Sensing current by measuring voltage across a resistor is simple and elegant, but issues arise with the electrical interface, sizing and selection, and thermal/mechanical considerations. Measuring ...

Designs requiring space-grade components must take into account the variances in component values that can occur over time. This is especially true for resistors, which can exhibit significant changes ...
