← ScienceWhich circuit malfunction results following dielectric breakdown in smoothing circuit capacitors?
A)Increased ripple amplitude at output✓
B)Lowered switching transistor gate voltage
C)Elevated inductor saturation temperature change
D)Reduced rectifier diode reverse bias
💡 Explanation
Dielectric breakdown causes capacitor shorts because the exceeded electric field surpasses insulating capacity leading to uncontrolled leakage. Therefore output ripple drastically increases, rather than correct smoothing because the capacitance is now ineffective under dynamic load.
