Which mechanism limits maximum data transfer rates in copper wiring?

A)Skin effect concentrates current flow
B)Oxidation increases insulator effectiveness
C)Increased electron mean free path
D)Cooper pair formation induces superconductivity

💡 Explanation

The skin effect restricts data transfer rates because AC current is forced to the wire's surface rather than the entire area. This reduces the effective cross-sectional area; therefore, resistance increases, rather than alternatives changing properties due to corrosion, carrier mobility, or temperatures.
