← ScienceWhich risk increases when a capacitor endures ripple current?
A)Premature electrolyte vaporization and swelling✓
B)Decreased dielectric constant, reduced capacitance
C)Localized piezoelectric resonance amplification
D)Runaway electron tunneling leakage currents
💡 Explanation
Capacitors, particularly electrolytics, generate internal heat from equivalent series resistance (ESR) during ripple current. This causes Electrolyte Vaporization because the dissipation factor rises with temperature, therefore the increased internal pressure leads to case swelling, rather than piezoelectric effects under normal operation.
