Question

The voltage V and current I graphs for a conductor at two different temperatures T1 and T2 are shown in the figure. The relation between T3 and T2 is (A) T1>T2 (B) T1 < T2 (C) T1=T2 (D) T1= (1/T2)

Resistance = Slope of V-I graph Resistance propto Temperature R1>R2 then T1 >T2

Q. The voltage $V$ and current $I$ graphs for a conductor at two different temperatures $T_{1}$ and $T_{2}$ are shown in the figure. The relation between $T_{3}$ and $T_{2}$ is

$T_{1} > T_{2}$

$T_{1} < T_{2}$

$T_{1} = T_{2}$

$T_{1} = \frac{1}{T _{2}}$

Resistance $=$ Slope of $V - I$ graph
Resistance $\propto$ Temperature
$R_{1} > R_{2}$
then $T_{1} > T_{2}$

Q. The voltage V and current I graphs for a conductor at two different temperatures T1​ and T2​ are shown in the figure. The relation between T3​ and T2​ is

T1​>T2​

T1​<T2​

T1​=T2​

T1​=T2​1​
