S r E ww R 2. When the switch S is open, the voltmeter V of the battery reads 3.05 V. When the switch is closed, the voltmeter reading drops to 2.88 V, and the ammeter A reads 1.57 A. Find the (a) emf, (b) internal resistance r of the battery, and (c) circuit resistance R. Assume that the two meters are ideal, so they don't affect the circuit.
