I'm working with a potentiometer in class. I'm using a 10V source: I have 2 1kΩ resistors in series: and a 1kΩ resistor and a potentiometer set to 2.56kΩ in series. And those two series are in parallel with each other. I don't understand why the measured value of the potentiometer is 2.56kΩ but when I measure it in the circuit, it reads 1.374kΩ. Why is there such a dramatic difference when it's read by itself and when it's connected to the circuit?
