Clark W. Griswold has been banned by his wife Ellen from anymore home lighting projects during the holidays… but she never saidanything about the car. Clark bought several boxes of 85W lightbulbs and wires them into strands of five bulbs each in series.
He then connects the strands to his 12V car battery (inparallel) and tapes them to the body of his stationwagon.  How many individual bulbs are used before Clarkblows a 5A fuse connected to the battery?
Note: Use 110V for wall voltage.
