Question

The I-V characteristics of a metal wire at two different temperatures (T1. and T2 ) are given in the adjoining figure. Here, we can conclude that (A) T 1 > T2 (B) T 1 < T2 (C) T 1 = T2 (D) T1 =2 T2

R increases with temperature and slope of V-I graph gives resistance so T1 < T2.

Q. The $I - V$ characteristics of a metal wire at two different temperatures $(T_{1}$ and $T_{2}$ ) are given in the adjoining figure. Here, we can conclude that

$T_{1} > T_{2}$

$T_{1} < T_{2}$

$T_{1} = T_{2}$

$T_{1} = 2 T_{2}$

$R$ increases with temperature and slope of $V - I$ graph gives resistance so $T_{1} < T_{2}$ .

Q. The I−V characteristics of a metal wire at two different temperatures (T1​ and T2​ ) are given in the adjoining figure. Here, we can conclude that

T1​>T2​

T1​<T2​

T1​=T2​

T1​=2T2​
