← ScienceWhich outcome occurs when a voltage spike exceeds ceramic capacitor's dielectric strength?
A)Capacitance value permanently decreases✓
B)Equivalent series resistance increases linearly
C)Self-resonant frequency shifts upwards
D)Thermal runaway increases operational lifespan
💡 Explanation
When voltage exceeds dielectric strength, dielectric breakdown occurs, forming a conductive path which damages ceramic structure, leading to permanently reduced capacitance due to shorts and material degradation. Therefore capacitance decreases, rather than resistance change, resonance shift or lifespan increase which follow temperature related stress.
