What is the function of a potentiometer?
The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.
What is potentiometer and its types?
There are two main types of potentiometer, linear potentiometers and rotary potentiometers. The mechanical construction of both rotary and linear potentiometers is very similar, each consists of two fixed terminals, one moving terminal (known as the wiper) and a resistive strip (otherwise known as a track).
What are 2 applications of a potentiometer?
Applications of potentiometer
- The potentiometer is used as a voltage divider in the electronic circuit.
- The potentiometer is used in radio and television (TV) receiver for volume control, tone control and linearity control.
- The potentiometer is used in medical equipment.
- It is used in wood processing machine.
What are precision potentiometers?
In simplest terms, a precision potentiometer is an electromechanical variable resistor typically used to sense change in position. It is typically used in a machine-to-machine interface (MMI) application and is thereby designed with high quality, durable materials for reliability.
Why do we use potentiometer instead of voltmeter?
The potentiometer is preferred over voltmeter when there is a measurement of emf of the cell because the potentiometer does not draw any current as it is a null device. Whereas voltmeter draws current from the cell.
What do potentiometers look like?
A potentiometer has 3 pins. Two terminals (the blue and green) are connected to a resistive element and the third terminal (the black one) is connected to an adjustable wiper. The potentiometer can work as a rheostat (variable resistor) or as a voltage divider.

What are Trimmer potentiometers?
A trimpot or trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits.
Is a potentiometer a transducer?
Transducer. Calling a potentiometer a transducer is a long stretch. A potentiometer is a variable resistor. A resistor is a passive device and clearly not a transducer. A transducer converts one form of energy into another. At best, a potentiometer can be used as a sensor, but turning it does not generate energy.
What is a Trimmer Potentiometer?
A trimmer potentiometer is a miniature adjustable electrical component. They’re designed for “set and forget” applications to “trim” the value of a resistor in order to provide an exact gain, output voltage, or current.
