Question : 23 of 30

Marks: +1, -0

A V-I graph for a nichrome wire is given below. What do you infer from this graph ? Draw a labelled circuit diagram to obtain such a graph.

Solution:

From the graph, we infer that as the current in the nichrome wire increases, the potential difference across it increases linearly. Thus, the graph follows the ohm's law.
