Question: When switch S in the figure is open, the voltmeter V of the battery reads 3.11V . When the switch is closed, the voltmeter reading
When switch S in the figure is open, the voltmeter V of the battery reads 3.11V . When the switch is closed, the voltmeter reading drops to 2.96V , and the ammeter A reads 1.65A . Assume that the two meters are ideal, so they do not affect the circuit.
E=3.110V
Find the internal resistance r of the battery. Express your answer in ohms to four significant digits.
