pls thnx me
Answer:
Potentiometer wire is normally made of alloy constantan or manganin due to their High resistivity and low temperature coefficient of resistivity.
Explanation:
A device with three terminals, two of which are connected to a resistance wire and the third to a brush moving along the wire, so that a variable potential can be tapped off: used in electronic circuits, esp as a volume control.
- Sometimes shortened to pot
These variable resistors are known as potentiometers when all three terminals are present since they act as a continuously adjustable voltage divider.
Digital potentiometers are versatile devices that you can use in many filtering and waveform-generation applications.
A potentiometer is a variable resistor in which a wiper sweeps from one end of the resistive element to the other, resulting in resistance that is proportional to the wiper's position.
