Prof. Insists that ohm's law goes one way only.
I am in an electronics and communications engg. Degree, and I have courses under this one prof who has taken three different courses across years, he starts his first lecture and never forgets to ask us about Ohm's law. And he insists that we must say "I(current) propotional to V(voltage)" and not the other way around because in real life current is always a consequence of voltage, and we don't have current sources that will consequently give voltage. Now I find this utter bs, because first of all a law is meant to be universal, which means even if you don't find any examples in support in real life, around you, even then the theory still holds. And second, I think the voltage sources are created as a result of some current flow only in the more traditional sources like the chemical batteries, the phenomenon is analogous to current flow?(As electron "flows" in the chemical process) Leading to storage of charges creating voltage difference. The reason we use voltage sources is just because of storage, current can't be stored as it's a flow.
If I were to argue, how can I even argue to this? Let me know if I am missing anything.
