By habit, I define the inductance of a circuit element as the ratio of "V
sub L" across that element to the rate of change of current in it, where
"V sub L" is the potential difference that appears only when the current is
changing. But lately I've noticed that currently popular textbooks tend to
define inductance as number of turns times flux divided by current. Is
there some reason to prefer this "flux-based" definition?
