I *think* this is what I was asking originally. If I add capacitance and Z
decreases, doesn't that mean that the initial X was inductive, and the
capacitance has cancelled some of it out? Does it not then follow that if
I continue to add C at a given frequency until Z stops decreasing and
begins to increase again, I've probably located X=0 and therefore Z=R?
Under what circumstances does X change sign without passing through 0?
