Youtube video, for the electrical types.

This professor is trying to confuse, bedazzle and impress rather than
teach or elucidate.

If he manages to spark CURIOSITY in a few more kids, isn't this A Good
Thing(tm)? He's teaching. Allow him some poetic license, please.

That did occur to me, but I think stimulating curiosity in a few while
confusing the hell out of most is elitist and not A Good Thing.

He schematically shows voltmeters connected near their respective
resistors while claiming that they are both connected to points A and
D. Schematically, they are. But schematically, a line conventionally
represents a node where voltage is everywhere the same. That isn't the
case here because EMF is induced in the wire he shows as a line in his
schematic. The razzledazzle is in interpreting the schematic
differently at different parts of his presentation while never
explicitly pointing that out.
