← ScienceWhich outcome occurs when repeatedly charging and discharging a capacitor?
A)Dielectric fatigue progressively lowers value✓
B)Electrode corrosion resistance increases sharply
C)Plate separation spontaneously reverses polarity
D)Equivalent series resistance surprisingly decreases
💡 Explanation
Dielectric fatigue is caused by repeated polarization reversals leading to gradual degradation of the insulating material; because molecular bonds within the dielectric break down, therefore capacitance decreases rather than electrode enhancements and the opposite effect on ESR and plate polarity.
