Question

1.Draw a V-I graph for a conductor at two different
temperatures. What conclusion do you draw from
your graph for the variation of resistance of the
conductor with temperature ?

Answer 1

Answer:

the graph shows that when temperature goes up, resistance goes up.

Answer 2

The V-I Characteristics stand for voltage-current characteristics of an electrical component or device.

In the above graph T1>T2 [graph is in photo]

The straight line A is steeper than the line B which leads us to conclude that the resistance of conductor is more at high temperature T1 than at low temperature T2. Thus we can say that resistance of a conductor increases with the increase in temperature.

From graph we can say that resistance of conductor increases with the increase in temperature.
