The \(I\) - \(V\) characteristics of a metal wire at two different temperatures \(\left(T_{1}\right.\) and \(T_{2}\) ) are given in the adjoining figure. Here, we can conclude that 
- A \(T_{1}>T_{2}\)
- B \(T_{1} < T_{2}\)
- C \(T_{1}=T_{2}\)
- D \(T_{1}=2 T_{2}\)
Answer & Solution
Correct Answer
(B) \(T_{1} < T_{2}\)
Step-by-step Solution
Detailed explanation
\(R\) increases with temperature and slope of \(V \cdot I\) graph gives resistance so \(T_{1} < T_{2}\)
