For an alternating current, inductance is an impedance (a general
term) or a reactance (a more specific term) - there will be a voltage
drop between adjacent windings, even if the resistance is zero. In
practical inductors, at the usual frequencies of interest, the
inductive reactance accounts for much more of the voltage difference
between windings than does the resistance.
