Potentiometer tutorial Circuit Diagram The output voltage will be taken across any one of the two input terminals and the sliding contact. The POT helps us to use variable voltages in the same device. Different Types of Potentiometers. The Potentiometer or POT is manufactured by using different types of materials like carbon composition, cermet, metal film, and conductive plastic.
Potentiometers are used in circuits to regulate the amount of current and voltage flowing through, allowing for precise control over the circuit's performance. To use a potentiometer in a circuit, one must first identify the electrical characteristics of the potentiometer and the circuit it will be used in. The shaft is connected to the wiper. Using one of the end terminals and the wipers, create a variable resistor to control or adjust current. Use all three terminals to create a voltage divider to control or adjust voltage. The following exercise illustrates how to wire a potentiometer to control voltage and current. \$\begingroup\$ A potentiometer can indeed regulate voltage. Or, rather, it can represent the input part of the closed loop for voltage control. A voltage meter provides the output, and a human operator turning the knob or moving the slider provides the control. \$\endgroup\$ -

We use potentiometers as voltage dividers or current limiters. With a voltage divider, we connect the power supply across the two end pins, and the wiper connects to the centre pin. This pin provides our output voltage. We can also use potentiometers for current control, we call this a rheostat. Potentiometers only have a small power rating
Additionally, there are shaftless potentiometers where the wiper is moved using an external tool such as a screwdriver, eliminating the need for a physical shaft. These are commonly referred to as trimmer potentiometers or trimmers. A potentiometer is a three-terminal device primarily used for voltage control, while a rheostat is a two
