Is A Potentiometer A Variable Resistor

A potentiometer is a widely used component of the electronic circuitit is used in different applicationsin this tutorial we will learn how can we use a potentiometer or pot as a variable. Think about it this way.

When wired as a potentiometer the wiper usually the middle connection acts as a tap.

Is a potentiometer a variable resistor. It functions as a potential divider and is used to generate a voltage signal depending on the position of the potentiometer. Potentiometer and rheostat are two terms that are associated with the variable resistors. One of the major mechanical considerations is the form of movement that creates the electrical changes in the variable resistor.

The potentiometer is the most common variable resistor. However by only connecting two pins one outside pin and one center pin of a potentiometer to your circuit you can turn a pot into a variable resistor. A potentiometer is a manually adjustable variable resistor with 3 terminals.

Technically both these terms represent the two different configurations provided by the same components. A potentiometer or pot for short is also known as a variable resistor. The potentiometer is filled with resistive material and turning the knob changes the amount of this material that the electrons must travel through before leaving the pot.

Heres a schematic to illustrate hgmjrs assertation. If only two terminals are used one end and the wiper it acts as a variable resistor or rheostat. Two terminals are connected to both ends of a resistive element and the third terminal connects to a sliding contact called a wiper moving over the resistive element.

Technically both these terms represent the two different configurations provided by the same components. A variable resistor is made up of a potentiometer wired with the center leg tied to one or the other end of the pot. The way in which a potentiometer or variable resistor moves can greatly affect the ergonomics of a piece of electronic equipment.

Variable resistors are used to dynamically change the resistance to control the current in a circuit and may also be used as a voltage divider. This permits it to act like a variable resistor. The potentiometer is a three wire resistive device that acts as a voltage divider producing a continuously variable voltage output signal which is proportional to the physical position of the wiper along the track.

For example they are used to control the volume in a radio. A potentiometer is a three terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
