Basically, it only applies in metals, not in semiconductors, or more appropriate, devices that current and voltage are non-linear. But it is ABSOLUTELY Ohm's Law. Does it apply in every instance, with every material? No. But it is still Ohm's Law, and is ABSOLUTELY correct to refer to that relationship: V=IR, as Ohm's Law.
Are you debating actual engineering concepts, or semantics?
Most any university engineering (electrical) professor (Ph.D) will tell you, and explain that it is in fact Ohm's law, fundamentally, when applied to metals. Once you get into semiconductors, and other materials, with a non-linear relationship, you will in fact start to see that it does not apply, but it is still HIS LAW. It is applied through observation.
"The greater the voltage, the greater the resulting current. For a large class of conductors, the current increases in direct proportion to the voltage.
Physical experimentation leads to the following equation: i = v/R, or, v=Ri, which is know as Ohm's Law. "

So, is the law wrong when concerning metals, or as it has been applied here in this thread?
Or, are you just debating semantics?
Seriously, no one in this thread is wrong in stating that those equations are Ohm's Law.....
An Ohm, is in fact, a Volt/Ampere.
