Q1. What is a potentiometer?
A potentiometer is a three-terminal variable resistor used to adjust voltage levels in a circuit. It works by varying resistance through a rotating or sliding contact.
Q2. What are the main terminals of a potentiometer?
A potentiometer has three terminals: two outer terminals connected to a resistive track, and one middle terminal called the wiper, which moves along the track.
Q3. What are the common types of potentiometers?
Common types include rotary potentiometers, linear (slider) potentiometers, and digital potentiometers.
Q4. Where are potentiometers commonly used?
Potentiometers are used in volume controls, light dimmers, motor speed control, and tuning circuits in electronic devices.
Q5. How does a potentiometer control voltage?
A potentiometer acts as a voltage divider. By adjusting the wiper position, it changes the output voltage between the wiper and one of the outer terminals.
