← ScienceWhich outcome reduces signal fidelity when high-frequency currents propagate?
A)Skin effect creates current crowding✓
B)Dielectric losses increase cable impedance
C)Capacitive reactance enhances signal matching
D)Inductive reactance cancels ground currents
💡 Explanation
The confinement arises because the skin effect increases current density at the conductor's surface, therefore raising resistance losses and reducing fidelity, rather than impedance changes or counteracting unwanted ground currents because it occurs at higher frequencies.
