hey, can anyone help me out with this question? im not getting the approach on how to do this. i found out the resistance of the two but how to compare it w temp?

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.For conducting wires, resistance is proportional to temperature
yes but we have to find the value of N, and we have not got the delta t value or alpha value in the q, so how do we do it mathematically?
In that case alpha x delta T must cancel out at some point
Or you can relate i^2R x t (heat) with the temperature increase
This assumes that the resistance is constant, so use this if alpha x delta T doesn't cancel out
okay thanks
