← ScienceWhich consequence results when excessive electrical arcing during circuit breaking generates extremely fast electrical wave phenomena?
A)Radiated Electromagnetic Interference increases✓
B)Switch contact resistance decreases
C)Capacitive transient immunity increases
D)Systematic harmonic filtering improves
💡 Explanation
Arcing initiates a rapid transient, thus electromagnetic interference radiates because the acceleration of charges during the current interruption triggers electromagnetic wave generation, therefore increasing EMI rather than other protective mechanisms, such as reducing contact resistance.
