Question

the voltage current graph of a metallic conductor at two different temperatures T1 and t2 is shown below at which temperature is Resistance hai​

Answer 1

Explanation:

The slpoe of given graph gives us the inverse of reaiatance. Resistance of a material inc. with increasing temp. becoz the collision b/w the molecules increases. In the graph given t2 haa smaller slope corresponding to higher resiatance...!

Hope this helps..! :)
