Jim,
Your last statement doesn't make any sense to me. I realize that reactance is an AC phenomenon but you say resistance is a DC phenomenon. Surely you aren't suggesting that resistance doesn't apply to AC?

Resistance is DC (as in E= I * R) . For AC, you need to talk impedance, which has a resistive and a reactive component; as in E = I * Z or I * (R + j X). And for AC, of non trivial, or non steady state single frequency systems, you need to worry about physical displacements, too.
