← ScienceWhich risk increases when pulsed power cables experience impedance mismatches?
A)Reduced standing wave ratio (SWR)
B)Increased antenna radiation efficiency
C)Premature cable dielectric breakdown✓
D)Enhanced signal propagation velocity
💡 Explanation
Premature cable dielectric breakdown increases with impedance mismatches because standing waves form as the reflected power propagates towards the source, causing localized voltage maxima along the cable. Therefore, breakdown is likely, rather than efficient signal propagation or improved matching characteristics.
