Question

flowing through it.
The voltage-current (V-I) graph of a metallic conductor at two different temperatures T1, and
T2, is shown below. At which temperature is the resistance higher?​

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..! :)
