Purpose: Find an unknown EMF using a voltage divider.
Description: A battery of voltage V is connected across a resistive wire of length L. A second, unknown lesser voltage battery is connected through a meter to the slide tap of the potentiometer. Find the distance L1 along the wire where the clip lead draws no current. The unknown voltage Vu is then: Vu=V L1/L External batteries can be used to provide a different battery configuration if desired.
