Problem A potentiometer is an instrument for measuring an unknown voltage in comparison to a standard voltage. In the potentiometer shown in Figure 1.0 a 16.0-m stretch of wire AB is connected to a 9.00-V battery. The resistance per unit length of the wire is 16.0 0/mm. The movable contact P is at point B. An ammeter (circle with A inside) is connected to point A. 16.0 m A B wwww Figure: 1.0 A V = 9.00 V 1. What is the total resistance of wire AB? Given: Solution: 2. What current does the ammeter read in milliamperes? Given: Solution:
