Hello everyone,
Can you guys please explain why a potentiometer needs a ground (-) wire? or what does it do differently and what uses there are for it as opposed to a rheostat.
Recently been playing around with automotive sensors like the TPS (Throttle Position Sensor) on a car and just can't understand why the manufacturer would put a potentiometer (3 wire sensor) over a simpler 2 wire sensor like the rheostat.
