Is a potentiometer analog or digital?

Potentiometers can be both digital and analog. An Analog potentiometer is a three-terminal resistor in which resistance is manually changed to control the flow of electric current. A mechanical or analog potentiometer is known as a pot because of its pot-like structure.

The digital potentiometer can automatically change resistance on the basis of a given condition. In a digital potentiometer, the resistance can be varied through digital communication.

Analog and digital potentiometers are interchangeable in many applications due to their similarities.
Both are adjustable and have a wide array of end-to-end resistance.
Analog potentiometer can withstand higher voltages and can carry a large current and have a larger dissipation of power.
However, analog potentiometers are highly sensitive to vibrations and shocks.
On the other hand, digital potentiometers can withstand wear and tear.
