← ScienceWhich outcome limits current capacity through a high-voltage transmission cable reliant on nanocrystalline aluminum oxide insulation?
A)Reduced efficiency during partial discharge
B)Dielectric breakdown from impact ionization✓
C)Increased skin effect at interfaces
D)Mechanical failure causes thermal runaway
💡 Explanation
Dielectric breakdown occurs at high voltages because impact ionization creates a cascade of charge carriers via electron acceleration within the aluminum oxide. This greatly increases current, therefore it is dielectric breakdown that limits capacity, rather than simply discharge or skin effect under normal usage.
