The intrinsic impedance of copper at high frequencies is (GATE 1998)

A)     Purely resistive
B)      Purely inductive
C)      Complex with a capacitive component
D)     Complex with an inductive component






Explanation: The intrinsic impedance is given by √(jwµ√ϭ + jw€). Since copper is a good conductor, ϭ << jw€, thus the intrinsic impedance will have +j component only. This refers to complex with an inductive component.
