More Information on Variable Resistors...
What is a Variable Resistor?
A resistor restricts current flow in an electrical circuit without switching the current off. A variable resistor allows more control over current flow by changing the amount of resistance. When resistance increases in a variable resistor, the amount of current that is allowed to flow in a circuit decreases. Two basic components make up variable resistors. The resistive material is the first component and is called the element. The second component, called the wiper or brush, is used to set the resistance, and is often controlled with a knob or sliding switch.
Types of Variable Resistors
There are several different kinds of variable resistors. At Future Electronics we stock many of the most common types categorized by Type, Number of Turns, Tolerance, Rated Power, Nominal Resistance and Packaging Type. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common sizes for Rated Power are 250 mW and 500 mW. We also carry variable resistors with Rated Power up to 37 W. Variable Resistors can be Potentiometer, Trimmer or Turns Counting Dial type.
