Modern NiMH rechargeable batteries of size AA have a maximum charge capacity of 2300 mAh and an emf equal to 1.20 V. A flashlight has three of these batteries connected in series. The 3.6 V bulb in the flashlight draws a current of 0.45 A. Assume that both the emf and the current do not change with time. Calculate how long the flashlight will operate using these rechargeable batteries.
