What are the differences between potentiometers and variable resistors?
Variable resistors come in two different basic varieties: potentiometers and rheostats. They differ slightly from one another. Typically, rheostats have two connections—one fixed and one movable. Any variable resistor is technically referred to as a rheostat. Three connections, two fixed and one movable, are always present on the potentiometer. Rheostats typically have a small range of values and a large current-handling capacity. Despite having a large range of values, potentiometers typically have a low current-handling capacity.
What are the top manufacturers of variable resistors?
Rohm, Arcol, Ohmite, Panasonic, YAGEO, AVX, Texas Instruments
What are the uses of a variable resistor?
Since the resistance of variable resistors can be adjusted to a certain value, they are frequently employed in electrical circuits to change the value of current or voltage. With variable resistors, you may change the resistance while maintaining a constant current to change the voltage value.
