Statement-1:- The temperature dependence of resistance is usually given as R=R_(0)(1+alpha Deltat) . The resistance of a wire changes from 100Omega to 150Omega when its temperature is increased from 27^(@)C to 227^(@)C . This implies that alpha=2.5xx10^(-3)//""^(@)C Statement- 2 :- R=R_(0)(1+alpha Deltat) is valid only when the change in the temperature DeltaT is small and DeltaR=(R-R_(0))lt lt R_(0)

The temperature coefficient of resistance of a wire is 0.00125^@ C^(-1) w.r.t temperature at 300 K at which the resistance of the wire is one ohm. Find the temperature at which the resistance of the wire will be 2 ohm.
