Skin Effect: AC’s Hidden Resistance Factor

This article explains the skin effect
a phenomenon where, in AC systems, most current flows near the conductor’s surface rather than through its full cross-section. It outlines how eddy currents oppose central current flow, pushing electricity outward, and why increasing frequency shrinks the effective conducting depth. Essential reading for understanding how this impacts conductor sizing and transmission efficiency. Learn more at: https://www.threephasetrai...
