Question

What is the shape of V – I graph for metallic wire? Why?​

Answer 1

Answer:

◾The slope of the graph depicts that Current and Resistance are Inversely proportional to each other ◾Due to the decreasing temperature , Resistance in a metallic wire increases due to more collisions between molecules .

Here is your answer

Hope it helped you!

Answer 2

Answer:

the shape of v - I graph for metallic wore is a straight line ,

as we know that the graph line represents the resistance of a conductor and by ohm's law v is directly proportional to the current ( I) so, it will be a straight line.
