← ScienceWhich effect occurs when rapidly switching a capacitive load?
A)Increased electromagnetic interference (EMI)✓
B)Decreased power supply ripple
C)Improved transient voltage suppression
D)Reduced ground loop currents
💡 Explanation
Rapid switching causes significant transient current spikes to charge/discharge the capacitor via displacement current, a form of Electromagnetic Induction. Therefore, significant radiation increasing EMI results, rather than the load improving power quality or voltage regulation under normal conditions.
