As [Electronoobs] points out, everything has resistance. So, how hard can it be to make a high-power resistor? In the video below, he examines a commercial power resistor and how to make your own ...

Power resistors come in all shapes, sizes, resistances and power ratings. Power ratings of discrete power resistors range from about 1W to 2.5kW. Resistances generally range from 0.01Ω to 100K. They ...

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 ...
