← ScienceWhich risk increases significantly when applying reversed polarity to the electrodes of a polarized electrolytic capacitor?
A)Dielectric material catastrophic breakdown✓
B)Increased equivalent series resistance
C)Diminished overall energy density
D)Decreased temperature coefficient efficiency
💡 Explanation
Applying reversed polarity to an electrolytic capacitor causes electrolysis of the electrolyte. This electrolysis generates gas, increasing internal pressure to the point of catastrophic rupture because the dielectric oxide layer dissolves, therefore breakdown is the significant risk, rather than other parameter degradation.
