← ScienceWhich risk increases when high voltage transmission experiences corona discharge?
A)Electromagnetic interference amplifies significantly✓
B)Line capacitance decreases substantially
C)Thermal resistance diminishes gradually
D)Conductor skin effect stabilizes quickly
💡 Explanation
Corona discharge causes radio wave generation; electromagnetic interference amplifies because the ionization of air creates erratic current pulses and high-frequency oscillations. These are source of electromagnetic radiation therefore resulting interference increases rather than reducing.
