Which consequence results when impedance mismatch occurs in high-frequency circuit breakers?

A)Reflected power increases heating events
B)Arc quenching efficiency improves rapidly
C)Switching harmonics are perfectly removed
D)Voltage standing wave ratio decreases

💡 Explanation

Reflected power increases losses when impedance is mismatched, because standing waves on the transmission line will cause constructive interference; therefore, more power is reflected back to the source in increased localized heating incidents, rather than traveling forward efficiently as intended.
