← ScienceWhich outcome results when a dielectric material within a high-voltage capacitor degrades under strong electric field?
A)Arcing due to reduced breakdown voltage✓
B)Increased capacitance due to polarization
C)Decreased leakage current due to insulation
D)Reduced ESR due to better conductivity
💡 Explanation
When a dielectric degrades, partial discharge ionization generates conductive pathways, reducing the breakdown voltage because the material's insulating properties weaken, leading to arcing. Therefore arcing occurs, rather than increased capacitance, decreased leakage, or reduced ESR which require different material properties or mechanisms.
