← ScienceWhich risk increases when voltage rises within coaxial cable?
A)Dielectric breakdown field strength exceeding✓
B)Capacitance decreasing due skin effect
C)Inductance shortens signal propagation velocity
D)Attenuation reduces signal reflection magnitude
💡 Explanation
Dielectric breakdown risk increases because excessively high voltage causes electric field strength to exceed the cable's insulation limit, instigating dielectric breakdown, therefore, causing cable damage, rather than lower capacitance because of increased skin effect under these conditions.
