← ScienceWhich outcome occurs when a high voltage, exceeding dielectric strength, is applied across electrodes coated in epoxy?
A)Dielectric breakdown through covalent bond rupture✓
B)Increased tensile strength material hardening
C)Enhanced thermal conductivity heat dissipation
D)Molecular alignment increases polarization
💡 Explanation
Dielectric breakdown occurs because voltage exceeding the dielectric strength causes covalent bond rupture, resulting in a sudden current surge therefore dielectric breakdown rather than any change in mechanical or conductivity characteristics because these rely on different mechanisms.
