Webb2 feb. 2024 · Skin effect increases the effective resistance of a conductor by reducing the cross-sectional area available for conducting current. In fact, the effective resistance offered by the conductor becomes more for AC than for DC. WebbSome of these shapes allow heat to dissipate more efficiently due to their high surface area to cross-sectional area ratio. The skin effect makes 50–60 Hz AC busbars more than about 8 millimetres (0.31 in) thickness …
