1i m serious da..........
don joke...........
its something abt transmission thro coaxial cables involvin frequencies.......
1It's the tendency of an AC current to distribute itself within a conductor 'coz of which the current density near the surface of the conductor is more than that at its core. implies, the electric current tends to flow at the "skin" of the conductor. It causes the effective resistance of the conductor to increase.
Skin effect is due to eddy currents set up by the AC current.
This is all what i've read in some b.tech notes... long backkk... ;)
correct me if i'm wrong...!!!
1i don kno anthin abt it...........
i wanted to clear ma doubt,,,.............
pls explain dis
d) is d ans...........
1high frequencies can be easily determined when resistance is high... since dielectric and skin effect increase d effective resistance of conductor with frequency of current, so they can help in determining high frequencies... :)
got...!!!
1Skin 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. That is, the electric current tends to flow at the "skin" of the conductor. The skin effect causes the effective resistance of the conductor to increase with the frequency of the current. Skin effect is due to eddy currents set up by the AC current.

1This could also be a, as at resonant frequency L and C dont offer any Reactance, Thereby allowing transmission of high frequency
