I think that it can be valid, so long as they aren't just telling you
to "do the math," but want you to think about what a law is saying to
get at the physics behind it.  I'm not sure that came across too well
in some of the replies to your original post (I'd have to think for
awhile about what Ohm's Law is telling me about the internal workings
of a battery).

Don't be afraid (being annoyed is fine, but not afraid).  This list
is aimed at physics educators, and as one, you are allowed to ask
*anything* involving physics education.  Don't go away unless you
think that the list is completely worthless or obnoxious (I
unsubscribed once myself because the tone of too many posts was
becoming very unpleasant).
