← ScienceWhich consequence results when dielectric breakdown in transmission lines?
A)Corona discharge power loss increases✓
B)Impedance matching becomes optimized
C)Skin effect attenuation diminishes
D)Magnetic field interference is shielded
💡 Explanation
Increased corona discharge loss occurs because ionization leads to higher conductivity near the conductor; therefore, dielectric breakdown raises power losses from corona discharge rather than improving impedance because it exacerbates field stress.
