Battery, Ammeter, and Resistors An ammeter is connected in series to a battery of voltage V₁, and a resistor of unknown resistance R₁ (Figure 1). The ammeter reads a current Io. Next, a resistor of unknown resistance R, is connected in series to the ammeter, and the ammeter's reading drops to I1. Finally, a second resistor, also of resistance R₁, is connected in series as well. Now the ammeter reads I2.
