This is a more complicated question than it seems on the face of it!Originally posted by haditya@Oct 1 2004, 11:24 AM
ill put it in another way
R2=R1[1+(alpha)(t2-t1)]
alpha here is called the temp coeff of reistance defined at a certain temp
i want to know at what temp is it defined and is the above formula valid for all temp t1 and t2, when alpha is defined for a value way out of the range of t1 or t2
in short i want to know if alpha is a function of temp with any definite mathematical relationship
