# Skin Depth Effect of Metal Calculator

Posted by Dinesh onThe skin depth is a defined depth used to approximate the effective cross sectional area of a conductor when the skin effect is limiting that area. The resistance of a metal segment will increase as frequency rises due to the skin depth effect.

The below table listed the conductor material's permeability values.

Conductor Material | Permeability Value (?_{0}) |
---|---|

Aluminium | 1.00002 |

Copper | 0.999991 |

Gold | 1.0 |

Nickel | 600 |

Silver | 0.99998 |

### Formula:

$\delta =\sqrt{\raisebox{1ex}{$\rho $}\!\left/ \!\raisebox{-1ex}{$\pi \mu f$}\right.}$

where,? is the skin depth

? is the frequency

? is the absolute magnetic permeability (?) = ?
