Hi,
I have been browsing previous threads and was intrigued by the very long thread on ohm's law. I have read most of the posts. I got confused on three things.
1. Ohm's law applies only with conductors or also with semiconductors?
2. The relationship V=IR or V=IZ is NOT a statement of ohm's law.
It is a resistance or impedance formula??
3. Ohm's law is a property of a material???
The formula V=IR is the first formula I learned in electronics. I believe it is basic. And I know that without full understanding of the basics, I can never learn fully the complicated things that are yet to come.
