Задача id9645

Two wires with equal resistances R = 20 Ohms are connected to the opposite poles of a battery, the emf of which is E = 120 V and the internal resistance is r = 10 Ohms. The free ends of the wires and their centers are connected to each other through two light bulbs with a resistance of R1 = 200 Ohms each. Find the current flowing through the battery and the current flowing through the light bulbs.
