My favorite example: "potential difference" in circuit theory. Engineers and anyone who actually builds or fixes electronics calls it "voltage."

Aaa ha!

Another one of those necessary false coincidences.

Check out the current AJP PER section paper.

"Probing university students’ understanding of electromotive force in electricity"


“… The results of the study show that student difficulties seem to be strongly linked to the absence of an analysis of the energy balance within the circuit and that most university students do not clearly understand the usefulness of and the difference between the concepts of potential difference and emf."

bc prays he’s not starting a “flame war”.

And note current “conversation: "[Phys-L] "conservative force" --> misnomer --> misconception

I’ve read as far as: "A series of non-conservative actions takes place in the battery …” , which prompted the above.
