MCQ

Electric power is transmitted over long distances through conducting wires at high voltage because

A
High voltage travels faster
B
Power loss is large
✓
Power loss is less
D
Generator produced electrical energy at a very high voltage A coil develops heat of $800 cal / sec$. When $20 volts$ is applied across its ends. The resistance of the coil is $(1 cal =4.2$ joule $)$

✓

Answer

Correct option: C.

Power loss is less

(c) Power loss in transmission $P_L=\frac{P^2 R}{V^2} \Rightarrow P_L \propto \frac{1}{V^2}$
