If you need a potentiometer for a project, chances are pretty good that you’re not going to pick up a pencil and draw one. Then again, if you’re teaching someone how a variable resistor works ...

There are certain important manufacturing factors that affect wirewound resistor properties. For example, the wire is wound under tension around a core, which can elongate the wire and alter its ...

The VRH320 Variable Wire Wound Resistor available from ARCOL Resistors has a wide range of applications for voltage and current adjustment including industrial machinery RPM adjustment ...

If the variable resistor's resistance increases, (V out) will decrease because more voltage is dropped across the variable resistor.

Variable power resistor (and why they wouldn’t let me in to art school) I need an adjustable power resistor that can be switched with a resolution of 1Ω. After some thought and web surfing, I bought ...

Very often when simulating an electrical circuit in SPICE, there is a need for a variable passive element such as a resistor, a capacitor or an inductor.
