Is a potentiometer analog or digital?

Hint: A potentiometer is a knob it provides a variable resistance,
It is a device that is used to calibrate measuring devices like ammeter, voltmeter, energy meter.
Potentiometers are generally used to control electrical devices like volume controls on audio equipment.

Complete answer:
The potentiometer is technically a variable resistor. The difference lies in how it is used in a circuit. Normally when you connect only two of its terminals, it is used as a variable resistance. If all three terminals are used, it is used as a potentiometer to vary the potential (voltage) across two points.
The potentiometer is a passive device, meaning they do not require a power supply or additional circuitry to perform their basic linear or rotary position function.
Potentiometers can be analog and digital. An Analog potentiometer is a three-terminal resistor here, the resistance of the potentiometer is changed manually to control the flow of electric current. because of its pot-like structure An analog or mechanical potentiometer is called a pot.
The digital potentiometer can change the resistance automatically which depends on the given condition. based on digital communication the resistance gets varied in a digital potentiometer

Note:
The potentiometer is a three-wire resistive device
A potentiometer acts as a voltage divider to generate a continuously variable voltage output signal
Here, it is used to measure the voltage, current, unknown resistance indirectly
It has two types are as follows,
1.polar type,
2. Coordinate type.
