An ammeter is connected in series to a battery of voltage V_b and a resistor of unknown resistance R_u (Figure 1). The ammeter reads a current I_0. Next, a resistor of unknown resistance R_r is connected in series to the ammeter, and the ammeter's reading drops to I_1. Finally, a second resistor, also of resistance R_r, is connected in series as well. Now the ammeter reads I_2. If I_1/I_0=4/5, find I_2/I_0
