    Tips: What is the difference between a rotary potentiometer and a potentiometer?

    A potentiometer, also known as a variable resistor or pot, is an electrical component used to control the flow of electric current. It has three terminals: a fixed terminal, a movable terminal (or wiper), and a common terminal. By adjusting the position of the wiper, the resistance between the fixed terminal and the wiper can be changed, thereby altering the amount of current flowing through the potentiometer.

    A rotary potentiometer is a specific type of potentiometer that is designed to be rotated. It consists of a circular or semicircular resistive element with a movable wiper that rotates along the resistive track. The wiper's position determines the resistance between the fixed terminal and the wiper, similar to a regular potentiometer. By turning the knob or shaft connected to the wiper, the resistance can be varied.

    In summary, the main difference between a rotary potentiometer and a potentiometer lies in their physical configuration. A potentiometer is a general term referring to any variable resistor with three terminals, while a rotary potentiometer specifically describes a potentiometer designed to be rotated, typically using a knob or shaft.
