Calculadora de Efeito Pelicular — Formula
## Skin Effect
**delta = sqrt(rho / (pi x f x mu))**
At high frequencies, current concentrates near the conductor surface. The skin depth is the depth at which current density falls to 1/e (37%) of the surface value.
Copper at 1 MHz: skin depth is about 0.066 mm.

Exemplo Resolvido
Copper at 1 MHz.
- rho = 1.72e-8 ohm-m
- mu = 4pi x 1e-7 H/m
- delta = sqrt(1.72e-8 / (pi x 1e6 x 4pi x 1e-7))
- delta = 0.066 mm
