While I do not know the specific book you reference, I can make two general notes:
1) It's basic science. As such, the 'facts' can't change, just the presentation; and,
2) It's simply not possible to completely understand alternating current unless you already understand calculus. The expression 'dx/dy' better mean something to you. This becomes critical, especially in understanding such things as impedance, harmonics, and power factor.
For 99% of the time, the simpler models used by electricians, based upon algebra, are adequate.
The fact remains that electricity, much like light, is still not completely explained by any existing model. We do know enough, though, to leave those puzzles to the ivory tower crowd.
