“…Theoretically it seems to be allowed to connect nonideal ammeters and voltage sources with certain nonzero internal resistances in parallel. (typically modelled by a resistor in parallel) and inductors can have considerable series resistance [3]. Thus, in theory, they could be used as resis tors in DC circuits just like the voltmeter in fig ure 1.…”

A recent physics challenge shows a circuit, where a voltmeter is connected in series. Indeed, real voltmeters have finite input resistance, therefore one may think that they can be used as resistors. In addition, voltmeters measure the voltage difference between their terminals, therefore it seems to be possible to calculate the current flowing through them. Is it okay? Does it make the voltmeter more universal? Are there any hidden secrets? How it is related to high-quality physics and STEM education, which are increasingly important in the modern world? Doesn't it approve an improper use that one can never see in any textbook and application? Suggesting and teaching such uncommon solutions doesn't generate undesired attitude? On the other hand, can it make the development of creativity and understanding harder if the students are taught to follow always the application rules? We do think it bears some discussion.
