In this tutorial you will analyse a solar powered Christmas tree. The tree has a solar panel at the top, a battery at the base, and bulb string lights around it. The bulb string lights are made from 4 parallel strings with 8 light bulbs in series each. Each light bulb has a nominal resistance of 8 2. The resistance of the wiring is negligible. The battery is charged during the day to keep the bulb string lights shining at...
