(part 1 of 5)
A string of 27 identical Christmas tree lights
are connected in series to a 120 V source. The
string dissipates 67 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)
What power is dissipated in a single light?
Answer in units of W
(part 4 of 5)
One of the bulbs burns out. The lamp has a
wire that shorts out the bulb filament when it
burns out, dropping the resistance of the bulb
to zero.
What is the resistance Rnew of the light
string now?
Answer in units of Ω
(part 5 of 5)
Part1
Voltage applied =120v
27 identical Christmas tree
Power dissipated =67 W
R=
R=214.93
Part 2
All are identical and connected in series
Resistance of single light ==7.96
