Question

What does a potentiometer measure?

Answer 1

Potentiometers work by varying the position of a sliding contact across a uniform resistance. In a potentiometer, the entire input voltage is applied across the whole length of the resistor, and the output voltage is the voltage drop between the fixed and sliding contact as shown below.Jan 31, 2019

1 Potentiometer. A potentiometer circuit can be used for comparing and measuring potential differences, the principle of action being that the unknown EMF is measured by balancing it against a known potential difference.
