The boiler heater consists of four sections. The resistance of each section is R = 1 Ohm. The heater is powered by a battery, the emf of which is E = 8 V and internal resistance r = 1 Ohm. How should the heater elements be connected so that the water in the boiler heats up in the shortest possible time? What is the total power consumed by the battery and its efficiency?
