A variable resistor is called a potentiometer or pot for short. They can also be used to control the voltage across devices in a circuit too.

What Is The Difference Between A Rheostat And A Variable

Considering their functions there are various types of these resistors to be found.

Variable resistor function. It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. Either side of the variable resistor may be attached to the circuit board with the remaining side unattached or grounded. A common type of variable resistor is found in the volume control on a radio.

It consists of a bare fixed resistance conductor with a terminal at each end plus a conductive wiper arm that moves along the fixed resistor to provide different resistance values. Answer a variable resistor may function as a potentiometer using three terminals or as a rheostat using two terminals. When the ends of the resistor track connect with inputs of circuits a variable resistor is used as a potentiometer.

Variable resistors can be used to adjust circuit elements such as a volume control or a lamp dimmer or as sensing devices for heat light humidity force or chemical activity. Definition of variable resistor. Rheostats are very similar in construction to potentiometers.

A digital variable resistor is a type of variable resistor. Rheostats are much related to the potentiometers in terms of construction. The potentiometer is the most common variable resistor.

As the resistance increases in the variable resistor the current through the circuit decreases and vice versa. They can be found inside many different types of electronic components and serve to protect them from too much current flow. Traditional variable resistors are continually altered as they work.

Types of variable resistors potentiometer. But when the potentiometer is wired as a rheostat only two connections are needed. It is an electronic component.

Presets are just like. Fixed resistors are the most common. A potentiometer is an ordinary variable resistor.

A variable resistor is the type of resistor which changes the flow of current in a controlled manner by offering a wide range of resistances. Its correct name is variable resistor while the terms potentiometer. The electrical resistance is varied by sliding a wiper contact along a resistance track.

When a potentiometer is used as a voltage divider all three terminals are wired separately. Types of variable resistors. A digital variable resistor is a type of variable resistor where the change.

When acting as a potentiometer all three of the devices terminals are being used. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment.
