Which of the following appropriately describes "Skin Effect"?
A. Current density decreases toward the center of the conductor so that for large wires the central portion is useless as a conductor, thus increasing the resistance of the wire above that which it would be for a continuos current.
B. The skin effect increases with the frequency and also the diameter of the wire in such a way that for the same percentage of increase in the resistance due to skin effect, the product (diameter^2 X frequency) is constant.
C. Both are true
D. Neither is true
Disclaimer: Any P.O.D. test questions are strictly fabricated. Any resemblace to actual test question, real or imagined, present or past, is strictly coincidental.
