A) Value of ratio \[\frac{V}{l}\]when the potential difference is 0.8 V is not equal to the value of ratio \[\frac{V}{l}\]when the potential difference is 1.2 V.
B) This graph illustrates the non-ohmic law.
C) While plotting this graph, the temperature remains constant.
D) All of these
Correct Answer: C
Solution :
The ratio of potential difference applied to the wire and current passing through it is a constant. Ohm's law is illustrated by this graph. Hence, temperature must be constant while calculating values.
