Question

State Ohm’s law. How can it be verified experimentally? Does it hold good in all conditions?

Answer 1

Explanation:

This law is only valid for ohmic conductor e.g. metals. Thus, is a constant, i.e., This verifies Ohm' law. 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.

Answer 2

According to Ohms law
Electric current flowing in a conductor is directly proportional to potential difference
V directly proportional to I
V=IR
Where R is resistance
It is not a universal law
It obeys only if physical conditions remain same
