In the transfer of electrical energy over power lines, it is desirable to minimize Joule heating by increasing the operating voltage. What prevents the energy company from stepping up the voltage to an extremely high level?
A) Corona discharge
B) Joule heating
C) Melting point of conductor
D) Latent heat of fusion of conductor

Question

Quizplus · Accepted Answer

Corona discharge becomes a significant issue at extremely high voltages, leading to energy losses. It occurs when the electric field around a conductor is strong enough to ionize the air near it, causing energy to be dissipated.
