What is Slide Wire DC Potentiometer Principles about?

This document describes the slide wire DC potentiometer. It operates by using a slide wire of uniform resistance and a battery to be measured. A current is passed through the slide wire and the voltage drop is compared to the battery voltage. By adjusting the position of the sliding contact along the wire until there is no current through a galvanometer, the ratio of voltages can be determined from the ratio of wire lengths. This allows both measurement of an unknown battery voltage and comparison of two ba
