Assertion : Current versus potential dif...

Assertion : Current versus potential difference (i-V) graph for a conductor at two different temperatures `T_(1)` and `T_(2)` is shown in figure. Hence `T_(1)gt T_(2)`.

Reason : Resistance of a conductor increases with rise in temperature.

A

`T_(1)gtT_(2)`

B

`T_(1)=T_(2)`

C

nothing can be said about `T_(1)` and `T_(2)`

D
