Assertion: Long distance transmission of a.c. is carried out at...

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

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step 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.
