A string of “holiday lights” contains 105 bulbs. The bulbs are connected in groups of 15 bulbs per leg of the string. Each group of 15 bulbs is connected in series. Further, each bulb has a resistance of about 60 Ohms. Each string of lights contains a 3 ampere fuse that all the current flows through. At the other end of the string of “holiday lights” is a socket to allow one to plug another string of holiday lights into. How many strings of lights can be plugged in such that only the first string of lights is plugged into a household socket and the fuse does not “blow?”
