← ScienceWhich outcome occurs when high surge current exceeds capacitor ESR limits?
A)Dielectric overheating and potential failure✓
B)Increased capacitance and faster discharge
C)Decreased internal resistance, optimized ESR
D)Stable voltage, capacitor performance improves
💡 Explanation
High surge current exceeding the equivalent series resistance (ESR) leads to joule heating via resistive **power dissipation**. This causes dielectric breakdown and potential catastrophic failure because excessive heat cannot dissipate quickly enough, therefore, overheating is the effect one sees due to current rather than an improvement as the capacitor degrades.
