Please complete all parts, each part is needed in order to complete the next question. The parts correaltes with eachother. (part 1 of 5) A string of 14 identical Christmas tree lights are connected in series to a 124 V source. The string dissipates 70 W. What is the equivalent resistance of the light string? Answer in units of Ω. (part 2 of 5) What is the resistance of a single light? Answer in units of Ω (part 3 of 5) How much power is dissipated in a single light? Answer in units of W (part 4 of 5) 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. What is the resistance of the light string now? Answer in units of Ω. (part 5 of 5)

(part 1 of 5)
A string of 14 identical Christmas tree lights
are connected in series to a 124 V source. The
string dissipates 70 W.
What is the equivalent resistance of the
light string?
Answer in units of Ω.
(part 2 of 5)
What is the resistance of a single light?
Answer in units of Ω
(part 3 of 5)
How much power is dissipated in a single
light?
Answer in units of W
(part 4 of 5)
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.
What is the resistance of the light string
now?
Answer in units of Ω.
(part 5 of 5)
Given Data
Power P = 70 W
Voltage V = 124 V
Current I to known,
Resistance R to be known.
