Battery, Ammeter, and Resistors An ammeter is connected in series to a battery of voltage V, and a resistor of unknown resistance R (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 R, is connected in series as well. Now the ammeter reads I2. Figure 1 of 1 a w Ru V R V (1) ww Ru < R 10 ww Ru R Part A If I1/10 = 4/5, find 1/10.
