- Skin effect
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The skin effect refers to the tendency of alternating current to flow near the surface of a conductor, with the current density decreasing exponentially with depth from the surface. This effect becomes more pronounced at higher frequencies.
