Answer / pyobik

skin effect is a phenomenon occuring in solid conductor
carrying AC supply, which leds the current to flow maximum
at the surface, this current density difference at the core
and the surface is due to the flux linkage in the core of
the conductor is more and leads to greater inductance
inside the core. And the skin effect occurs!
and the inductance is dependent on the frequency.

Answer / pandi

the conductor carrying a.c current more current fiow
through outer surface because more inductance in centre of
the conductor.inducdance value is depent upon frequency.
XL=2*3.14*f*L

Answer / divya kumar sharma

The cause of skin effect is as said in above answers.
Also we have inductive reactance proportional to frequency,
hence skin effect is pronounced at higher frequency.

another answer may be that inductance is proportional to
rate of change of flux linkages with respect to current. as
frequency increases change in flux linkages also increases,
L increases, Xl increases, skin effect is more pronounced.

Answer / rk

Rac is allways greater than Rdc due to skin effect which in
diactes less the freq less will be inductance and the
current will pass throug the entire cross sec area of
conductor.
