Question: Electric power is transmitted over long distances through conducting wires at high voltage because
[MP PET 1994]
Options:
A) High voltage travels faster
B) Power loss is large
C) Power loss is less
D) Generator produced electrical energy at a very high voltage
Show Answer
Answer:
Correct Answer: C
Solution:
Power loss in transmission $ P _{L}=\frac{P^{2}R}{V^{2}} $
Therefore $ P _{L}\propto \frac{1}{V^{2}} $
