I-V graph for a given metallic wire at t...

I-V graph for a given metallic wire at two temperatures `T_1` and `T_2` is as shown in Fig. Which of the two temperatures is lower and why?

Text Solution

Verified by Experts

At lower temperature resistance of metallic wire is less or slope of I-V graph is more. Hence, `T_1 lt T_2` .
