Discover the power dissipated by the string

Reference no: EM13657954

A string of 18 identical holiday tree lights is connected in series to a 190V source. The string dissipates 62.0 W. One of the bulbs burns out. The lamp has a wire that shorts out the lamp filament when it burns out. This drops the resistance of the lamp to zero.

a) Discover the power dissipated by the string.

b) What is the resistance of the light string now?

c) Did the power go up or down when a bulb burned out?
