Two fixed pins and one moving pin can be identified from the circuit symbol. This is the latest variable resistor circuit symbol specified by the national standard. The letters in RP represent the variable resistor. Figure 1. Circuit Symbol of Variable Resistor Many existing circuit diagrams do ...
PURPOSE:To make a DC level of an output signal stable and to improve the distortion of a current in a voltage current characteristic by supplying a current of a constant current circuit controlled by a variable resistor to a current mirror circuit to vary a constant current of a differential ...

In the case of a sensor type variable resistor, you can set up a voltage divider, so when the voltage drop across the sensor reaches a certain point a separate circuit is enabled to do something else, often with the use of an op-amp comparator. Variable Resistors Application Variable resis...
Design of a floating node voltage-controlled linear variable resistor circuit The floating node voltage-controlled linear variable resistor circuit is a versatile building block in several analog signal processes such as telecommunications and electronics. Floating node voltage-controlled linear variable resist...
How to use a preset? There are 3 pins/terminals on a preset. The maximum resistance that a preset can provide is written on it. If 100K is written on preset, it means that we can vary its resistance from 0 Ohm to 100K. A movable metal is rotated in clockwise or anticlockwise directi...

The resistor RFCL and inductor LFCL form a shunt path, which provides impedance to limit the fault current when the IGBT switches out to drive the flowing current to the shunt path. When a fault is detected, the FCL is switched in by shutting down the IGBT path. The impedance of the ...
Preset Symbol Most of the variable resistors are placed directly on the PCB. Some are mounted by drilling a hole in the case containing the circuit and is connected to the terminals with the help of a wire. In recent years, the size as well as the weight of such devices have been great...
