Ohmic resistance is independant of frequency R=V/I
simply.But for effective resistance X(L)=2*3.14*F*L
(Inducatance)and for capacitance X(C)=1/2*3.14*F*C Which
are depending upon the frequency.

Answer / thanigai1984

ohminc resistance is R value... and the effective
resistance is impedance z=suare root of R+XL
