Is this Ohm's law?

[v0031]

Using equipment of his own creation, Ohm determined that the current that flows through a wire is proportional to its cross sectional area and inversely proportional to its length or Ohm's law.

欧姆用自创的设备，证明了通过一段电线的电流和它的横截面成正比，和电线的长度成反比。

Is above Ohm's law? Different from what I was taught.

I'm not sure if my translation is correct or not.
