← ScienceWhich outcome reduces capacitive charge when dielectric is stressed?
A)Partial discharge erodes insulator volume✓
B)Increased dielectric constant raises inductance
C)Temperature coefficient stabilizes capacitance peak
D)Improved cooling extends dielectric breakdown
💡 Explanation
Partial discharge causes erosion because ionization of the dielectric material locally breaks down, reducing its effective volume; therefore, capacitance drops by reducing the effective plate area, rather than breakdown with increased dielectric strength.
