Question

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.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

Reason is false. When voltage is extremely high, current is extremely weak. Therefore, energy loss in long distance transmission of a.c. becomes negligible.
