The skin effect of a conductor will reduce as the__________?
Correct answer: A. resistivity of conductor material increases
- A. resistivity of conductor material increases
- B. permeability of conductor material increases
- C. diameter increases
- D. frequency increases
Explanation
Skin effect becomes weaker when resistivity increases because the skin depth is proportional to the square root of resistivity. Higher permeability, diameter, or frequency makes current crowding at the surface more pronounced.
