"The skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core."
The reason it is dubbed the 'skin effect' is due to the fact that electric current running through a wire (or other conductor) will more than likely run through the surface ('skin') of the wire before it would run through the core.
According to Wikipedia, it states that "the skin effect causes the effective resistance of the conductor to increase with the frequency of the current." Apparently, the skin effect also tends to occur at higher frequencies (above audio range).
To avoid the skin effect, it is suggested to use "stranded rather than solid wire" ( http://whatis.techtarget.com/definition/0,,sid9_gci541369,00.html# ).
What part of learning about the skin effect are you interested in? It is hard to answer a vague question. It seems like if you wanted a definition you would have looked it up already...
Skin effect is the tendency of ac current to flow near the surface where the flux linkages are low and the resitance component contributing to impedance .Higher the frequency skin effect resistance is high.This principle is used cage motors for getting a high starting torque.To overcome skin effect stranded conductors are used.
