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 ...

A variable resistor that integrates a programmable, temperature-indexed look-up table can compensate for the temperature drift of a voltage regulator. In this case, the look-up table can change the ...

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 ...

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 ...

TT Electronics has aded four new product families to its variable resistor portfolio. These include three new encoder lines and a new line of single turn potentiometers. These products are suitable ...

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

When current passes through a resistor it generates heat, and the thermal reaction causes mechanical changes by differential expansion in the different materials. Ambient conditions have the same ...

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.
