Skin effect calculator is an online tool for electrical and electronic circuits to measure the Skin Depth. In Transmission Line, the tendency of alternating current flow highly concentrate to near the outer surface than the inner depth of a conductor is called as Skin Effect. In identical conductor, the current flow and density will be equally passing over the entire cross section area of a conductor. According to Faraday's law the changing current in one conductor causes a changing in magnetic field that induces a current in the opposite direction in an adjacent conductor. The depth of the conductor is used to calculate the Skin Effect. When it comes to online calculation, this Skin Effect calculator can assist you to assess the Skin Depth σ based on the given frequency. The current displaced more and more to the outer surface with high frequency alternating current. It can be reduced by increasing width of the conductor.
