A set of Christmas tree lights consists of 60 identical bulbs connected in series. When they are connected to a constant 240 V electricity supply, the bulbs dissipate 2.00 W of electrical power each. In an attempt to improve performance, an amateur electrician decides to remove 10 bulbs and replace them with connections of effectively zero resistance. Assuming that the bulbs do not burn out, how much power is dissipated by the total set of bulbs when the modified set is switched on?

Answer is 144 W
