← ScienceWhich outcome occurs when a high-voltage electric field exceeds the dielectric strength within epoxy resin?
A)Covalent bond breakdown and carbonization✓
B)Increased hydrogen bonding stabilizes structure
C)Ionic bond enhancement lowers conductivity
D)Molecular orbital rearrangement prevents arcing
💡 Explanation
Covalent bond breakdown within the polymeric epoxy leads to arcing because electron avalanche causes impact ionization; therefore the resin carbonizes leading to tracking failure, rather than enhanced insulating ability due to stronger hydrogen or ionic bonding.
