Question

V-I graphs for two wires plotted at a given temperature are as shown below.For common potential difference applied acros them,(voptage of wire 1 is more than wire 2,current of wire 2 is more than wire 1)

Answer 1

This is an I-V graph so the slope must represent 1 R 1R Now, R ∝ T e m p e r a t u r e R∝Temperature {This is assuming that the wires are of metal} Now , since the graph is of 1 R 1R , the steeper the slope the higher I and lower R Thus, wire 2 has a higher temperature. Is my solution all right?
