← ScienceWhich electromagnetic effect occurs when rapidly discharging capacitive smoothing elements in power supplies?
A)Electromagnetic Interference propagates extensively✓
B)Dielectric breakdown becomes primary concern
C)Electrostatic discharge permanently alters
D)Capacitance subtly improves over time
💡 Explanation
EM interference increases massively because displacement current surges during rapid discharge, initiating intense radiation; therefore, EMI propagates rather than dielectric breakdown, which requires slower accumulation, or capacitance improves under normal conditions.
