Statement I : The temperature dependence of resistance is usally given as R=R_(0)(1+alphaDeltat). Theresistance is 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 II : R=R_(i)(1+alphaDeltaT) is valid only when the change in the temperature DeltaT is small and DeltaR=(R-R_(0))ltltR_(0) |
