PhysicsEasysingle choice

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

Options:

Answer:

Solution:

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