← ScienceWhich mechanism limits data transmission rate when high frequency signal propagates through coaxial cable?
A)Skin effect increasing conductor resistance✓
B)Dielectric breakdown reducing signal integrity
C)Electromagnetic interference causing signal corruption
D)Signal reflection creating standing waves
💡 Explanation
At high frequencies, the skin effect concentrates current near the conductor's surface because of self-induction generating opposing fields, thus increasing the effective resistance which attenuates the signal reducing data throughput. Therefore the skin effect limits data rate, rather than dielectric breakdown, interference, or signal reflections which require alternative conditions.
