← ScienceWhich outcome reduces transmission efficiency in high-voltage AC power lines?
A)Increased corona discharge near conductors✓
B)Decreased inductive reactance of lines
C)Lowered skin effect within conductors
D)Minimized dielectric losses in insulators
💡 Explanation
Rising AC voltage gradients near conductors initiates **ionization** of air; because of this, electrons accelerate and collide, emitting light and generating heat at radio frequencies. Therefore, corona discharge increases, rather than inductive reactance falling or any reduction in skin effect.
