Skin Effect Calculator
Calculate the skin depth in a conductor at a given frequency, which determines effective current-carrying area at high frequencies.

Skin Depth vs Frequency
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.
Example Calculation
Copper at 1 MHz.
- 01rho = 1.72e-8 ohm-m
- 02mu = 4pi x 1e-7 H/m
- 03delta = sqrt(1.72e-8 / (pi x 1e6 x 4pi x 1e-7))
- 04delta = 0.066 mm
