Question
potential difference-current graph for given wire at a fixed temperature is
Solution
The potential difference-current graph for a given wire at a fixed temperature is a straight line passing through the origin. This is due to Ohm's law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points. The slope of the line is the resistance of the wire, which remains constant at a fixed temperature. Therefore, the graph is a straight line with a slope equal to the resistance.
