← ScienceWhich failure consequence occurs when exceeding capacitor ripple current limits?
A)Electrolyte boiling and case rupture✓
B)Dielectric breakdown with voltage spikes
C)Decreased equivalent series resistance (ESR)
D)Increased capacitance and energy storage
💡 Explanation
Exceeding ripple current limits causes *Ohmic heating* within the capacitor. Because the internal resistance dissipates energy in the form of heat, electrolyte temperature rises rapidly, leading to boiling and case rupture faster than other failure modes.
