Topics covered in this informative video: potentiometer, electrical engineering, basic electronics, what is a resistor, resistors in series, variable resistor, power electronics, current limiting, Carbon film, carbon composite, Metal film, Potentiometer, Thermistor, RTD, LDR, Light dependant resistor, SMD, rheostat and much much more.

The video often (not always) describes resistors as coiled wires. Don’t they induce magnetic fields and currents in other components? This article answered these questions for me: eepower.com/…/resistor-inductance/#

TL;DR: Yes, but the effect is often negligible or the application does not care. When it matters, we can minimize the effect with appropriate designs (i.e. without coiled resistors).
