Question

Advantages and disadvantages of potentiometer in potentiometry experiment

Answer 1

Potentiometers, or pots, are adjustable resistors having a contact that moves across a resistive element. Some have a rotary action, and others are linear. This motion involves friction between internal parts, and leads to wear and noise. While designers use pots as inexpensive, easy-to-use electronic controls, wear and inertia limit their usefulness as sensors in mechanical systems. Over decades, potentiometer materials have improved, but these fundamental problems still exist.
