Assertion (A): AC load line is used for long distance transmission.
Reason (R): It has very less loss of energy in long distance transmission.
Answer:
AC load line is used for long distance transmission because power dissipation (loss of energy) in AC is lower since frequency is high.
Thus,
- Assertion is true.
- Reason is true.
- Reason is the correct explanation for Assertion.
So, the correct answer is (a)
