← ScienceWhich outcome occurs when a high-frequency signal encounters a partially open coaxial cable?
A)Signal reflection and impedance mismatch.✓
B)Increased signal velocity and bandwidth.
C)Reduced dielectric breakdown voltage rating.
D)Enhanced skin effect with higher conduction.
💡 Explanation
Signal reflection and impedance mismatch occur because discontinuity causes a change in impedance; this affects impedance matching. Power from the propagated wave reflects back towards the source, rather than being fully transmitted, therefore signal strength decreases; this is unlike enhancement of conduction.
