:::::::::(edit conflict - composed before you changed the above para, so replying to what it used to say) Well you're right I like the brevity, but I have a problem with Wikihow, at least in the way you are trying to use it.  Wikihow is not a Wikimedia sister project and so links to it count as external links which should not be used in the body of an article (WP:ELPOINTS).  Of course there are always exceptions to any rule, but I don't think we should make any exceptions for a site that carries advertising.  If you can find a way of getting the material onto Wikibooks on the other hand, not only is linking acceptable, but templates are provided for this purpose - Template:Wikibooks, or you can link with b:.  Don't really like the change of title, it is not the presence of reactance that causes difficulty with Ohm's law but the nature of the driving signal - ie varying.  Since the s-operator notation covers all signals, not just steady state sinewaves, the title is "transients and ac".
