Understanding Ohm's law

All of us have studied OHM's law at some point of time in our life and yyet we don't exactly understand it. This I understood when I was teaching Ohm's law to my students. Different books and authors take different approaches and interestingly they all incorporate a fundamental flaw. This flaw is both physical and mathematical.
So I am writing a small paper to bring forward the two methods and the mistakes that most authors and teachers of physics make while teaching students the physics of electricity and especially Ohm's law and resistance.
