hey guys
here is my question

⏩state Ohm's law .how can it be verified experimentally? does it hold good under conditions ?⏪

Answer 1

Ohm's law does not hold good under all conditions as it is not a fundamental law of nature like Newton's law. It is obeyed by metallic conductors only when physical conditions like temperature etc. are kepi unchanged

Answer 2

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. ... More specifically,

Ohm's law states that the R in this relation is constant, independent of the current.
V=I*R

It is workable only under constant temperature
