Web24 Jun 2024 · A potentiometer is an instrument we use to measure voltages. It measures the voltage by comparing a known voltage with an unknown voltage. If we use a highly sensitive instrument, then we have to draw a little current through the source having the unknown voltage. The known voltage is “the reference voltage”. WebIn the early days of potentiometer sensors technology, wire-wound potentiometers were often utilized as big and chunky regulating resistors. In the sixties, the use of fine wire potentiometers became much more common as performance and life time improved – modern wire wound potentiometers provide very good linearity
