An LED camping headlamp can run for 18 hours, powered by three AAA batteries. The batteries each have a capacity of 1000 mAh, and a terminal voltage of 1.5 V, which you can assume to be constant over the full discharge range. The batteries are connected in series, so that the total battery pack voltage is the sum of the individual cell voltages.
a. What is the power consumption of the LEDs?
b. How much current do the LEDs draw?
