Industrial controls and variable-bias circuits sometimes require the services of voltage-to-resistance converters. But they can be difficult to implement. The simple approach shown in the figure ...

Gear Potentiometers are also called Thumbwheel Potentiometers. Let’s investigate them. There are many varieties of compact gear potentiometers available. Most of them are single and dual – this time ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...
