Options

Choose one · Correct answer highlighted

Explanation

Power loss in lines is P_{loss = I² R . For a given power ( P = V I ), increasing V reduces I ( I = P / V ), significantly lowering I² R losses. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
