← ScienceWhich outcome disables protection circuitry during capacitor discharge?
A)Increase in electromagnetic interference (EMI)
B)Dielectric breakdown of oxide layers✓
C)Excitation of substrate's standing acoustic waves
D)Depletion of thermal transport capacity
💡 Explanation
Dielectric breakdown occurs because the electric field exceeds material strength, causing ionization and conductive paths throughout the insulator. Therefore, a current surge exceeds control capacity, rather than an intended current limit for protection, and damages downstream components.
