A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...

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...
