If the switch (S) in the figure is closed for a very long time, what is the charge on the capacitor? Use an emf of 20 V, R1 = 100 Ω and C1 = 20 μF.
When switch S in Fig. E25.33 is open, the voltmeter V of the battery reads 3.08 V. When the switch is closed, the voltmeter reading drops to 2.97 V, and the ammeter A reads 1.65 A. Find the emf, the internal resistance of the battery, and the circuit resistance R. Assume that the two meters are ideal, so they don’t affect the circuit.
