← ScienceWhich mechanism limits charge accumulation in spark plug capacitance?
A)Dielectric breakdown minimizes saturation✓
B)Eddy current maximizes back EMF
C)Electrostatic induction reverses polarity
D)Joule heating decreases resistance
💡 Explanation
Dielectric breakdown causes sudden discharge because exceeding the dielectric strength creates a conductive path, mitigating charge accumulation, rather than alternatives. It prevents further charge storage under high potential differences; therefore dielectric breakdown is correct.
