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.
Official answer
The graph shows a straight line passing through the origin, indicating that the current flowing through the nichrome wire is directly proportional to the potential difference across it. This is in accordance with Ohm's Law, which states that the current flowing through a conductor is directly proportional to the potential difference across its ends, provided the temperature remains constant.
