An ammeter is connected in series to a battery of voltage
Vb and a resistor of unknown resistance Ru(Figure
1) . The ammeter reads a current I0. Next, a resistor of
unknown resistance Rr is connected in series to the
ammeter, and the ammeter's reading drops to I1. Finally, a
second resistor, also of resistance Rr, is connected in
series as well. Now the ammeter reads I2.
