My last post on how [latex]V=IR[/latex] is not Ohm’s law received some comments. @dodiscimus said: “And [latex]F=ma[/latex] is not Newton’s 2nd law. Your next post?” I’m quoting him to: give him the credit for having the idea and spotting the similarity (see later) share the blame – otherwise people are going to think all I […]

Why V=IR is not Ohm’s Law, and why that matters
I have lost count of the number of times I have heard people say that Ohm’s Law is [latex]V=IR[/latex]. I have seen it in lots of electrical training materials. This post is to explain that Ohm’s Law and [latex]V=IR[/latex] are not the same thing, and that the difference matters; thinking they are the same is […]
