A string of 20 identical Christmas tree lights are connected in series to a 120 V source. The string dissipates 59 W. What is the equivalent resistance of the light string ? One of the bulbs quits burning. The string has a wire that shorts out the bulb filament
when it quits burning, dropping the resistance
of that bulb to zero. All the rest of the bulbs
remain burning
