Answer 1

Answer:

(i) Inference : V ∝ I

 

(ii) It states that the current passing through a conductor is directly proportional to the potential difference across its ends, provided the physical conditions like temperature, density, etc, remain unchanged. This is ohm’s law.

 

(iii) Slope : Resistance, unit ohm.
