							Yes it can be possible through skin effect.Skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductor such that the current density
 is largest near the surface of the conductor, and decreases with 
greater depths in the conductor. The electric current flows mainly at 
the "skin" of the conductor, between the outer surface and a level 
called the skin depth. The skin effect causes the effective resistance of the conductor to increase at higher frequencies
 where the skin depth is smaller, thus reducing the effective 
cross-section of the conductor. The skin effect is due to opposing eddy currents induced by the changing magnetic field resulting from the alternating current.
