If the frequency is increased, then the skin effect will

A. Decrease

B. Remain the same

C. Increase

D. None of the above

Answer: C. Increase

Explanation:

The skin effect is inversely proportional to the skin depth.

The skin depth is given as

skin depth = 1/√(πfµσ) where

f = frequency

µ = permeability

σ = conductivity

So by increasing the frequency, the skin depth decreases, and the skin effect increases.
