I want to know ohm's second law i search many times about it but every time the result is about ohm's first only, so can anyone help me??

I had not previously heard of ohms second law. As near as I can tell, one takes ohms "first" law and divides each side by R. Not very interesting...but useful

Doesn't the fact that you can't find anything with a search give you a clue that there IS no such thing?

I worked in the field of analog, control, and power supply circuit design for about 30 years and I never heard of "Ohms 2nd law", so I guess I can't help.

What I can say though is that it isn't the name of the law that matters, it's the information conveyed. I still couldn't tell you with certainty which is Newton's 2nd law of motion vs. his 3rd law. But I do know the material, and that's what matters.

Then, as a wild guess, I'd say that if ohm's first law is V=I⋅R, then his second law is probably I=V/R. Ohm didn't do much else in the world of physics or electronics; as far as I know, anyway.
