The dynamo has e. d.s. E1 = 12 V. Its internal resistance r1 is 0.2 ohm. It charges the battery with e. d.s. E2=10 V and internal resistance r2 = 0.6 ohm. A light bulb with a resistance of R = 3 ohms is connected in parallel to the battery. Determine the currents in the battery and in the light bulb.
