← ScienceWhich limitation arises as signal frequency increases within RF transmission lines?
A)Dielectric losses increase exponentially
B)Skin effect resistivity escalation✓
C)Capacitive reactance increase sharply
D)Magnetic field shielding degrades rapidly
💡 Explanation
Increased frequency forces current to flow on the surface (skin effect mechanism) because higher frequency causes greater self-inductance impeding current flow near the center. Therefore, the conductor's effective cross-sectional area decreases, rather than increased dielectric loss being dominant.
