The voltmeter V reads 3.11V, when switch S is open . When the switch is closed, the voltmeter reading drops to 2.88 , and the ammeter A reads 1.61. Assume that the two meters are ideal, so they don't affect the circuit. Find the internal resistance of the battery. 2.34 ohm 0.98ohm 0.14 ohm 0.52ohm 1.23ohm
