The current (I) and voltage (V) graphs for a given metallic wire at two different temperature `(T_(1))` and `(T_(2))` are shown in fig. It is concluded that

A

`T_(1) lt T_(2)`

B

`T_(1) gt T_(2)`

C

`T_(1) = T_(2)`

D

`T_(1) = 2T_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Slope of graph `V-I = (1)/("Resistance")`
`R_(2) gt R_(1)` So` T_(2) gt T_(1)`
