Assertion: Long distance transmission of a.c. is carried out at extremely high voltages. Reason: Because when the distance is large, voltage has to be large.
Options:
Answer:
B
Solution:
Reason is false. When voltage is extremely high, current is extremely weak. Therefore, energy loss in long distance transmission of a.c. becomes negligible.
