MCQ
Electric power is transmitted over long distances through conducting wires at high voltage because
- AHigh voltage travels faster
- BPower loss is large
- ✓Power loss is less
- DGenerator produced electrical energy at a very high voltage
✓
Answer
Correct option: C.
Power loss is less
c
(c) Power loss in transmission ${P_L} = \frac{{{P^2}R}}{{{V^2}}}$ $ \Rightarrow $ ${P_L} \propto \frac{1}{{{V^2}}}$
(c) Power loss in transmission ${P_L} = \frac{{{P^2}R}}{{{V^2}}}$ $ \Rightarrow $ ${P_L} \propto \frac{1}{{{V^2}}}$
