Hello Deyan and all, I’m a bit puzzled. “Electrical Engineering” is not a specialty I’d expect within K12. You become electrical engineering after choosing after k12. Am I wrong? So, the differentiatiation between i and j is not k12. 12th year is kind of an advanced period anyways. We did have complex numbers and an amount of other advanced topics such as linear algebra or differential geometry but we did not have the named electrostatic constants. It appears that almost all differential geometry we had is no more in normal standards but probability and statistics now are (even going as low as 4th grades, 10y old!). It’ll be impossible to not be partial as an expert. I think. And we should accept this.

Which is just my expedient heuristic to check if something is ubiquitous in educational materials. So while it is quite hard to meaningfully compare if they are more or less common than "mean" and "median" (and to whom? an electrical engineer may have a different answer), at least they fit the K-12 designation. Another point is that since they have natural self-voicing speech, it is possible they fit better as ":property" annotations. But I think that is still an open question - they should likely get the same treatment that the imaginary-unit (i vs j) would get, whichever direction we decide that. > > [1] https://www.khanacademy.org/science/in-in-class-12th-physics-india/in-in-electrostatic-potential-and-capacitance/x51bd77206da864f3:capacitance-parallel-plate-capacitors/a/capacitors-article > > [2] https://www.khanacademy.org/science/physics/magnetic-forces-and-magnetic-fields/magnetic-field-current-carrying-wire/a/what-are-magnetic-fields
