Harmonic Filter Resistors
The purpose of a harmonic filter is to reduce distortions in power systems, produced by arc welders, induction furnaces, VFDs, ballasts, computers, UPSs etc., which can cause failure of motors, transformers and switchgear through insulation breakdown, arcing and overheating. more...
 
 
Resistor Elements
A resistor element is a two-terminal electrical or electronic component that opposes an electric current by producing a voltage drop between its terminals in proportion to the current. The power dissipated by a resistor is the voltage across its body multiplied by the current flowing through it. more...
 
 
Potentiometers
A potentiometer is a variable three-terminal resistor that can be used as a voltage divider. Potentiometers are commonly used as controls for electrical devices and electronic circuits. more...
 
 
Rheostats
Rheostats are two-terminal variable resistors generally used as variable resistors rather than variable potential dividers. Often these are designed to handle much higher voltage and current than potentiometers. more...
