Homework Help: Physics - electricity

Posted by Damilola on Tuesday, April 17, 2007 at 3:34am.

A thermo junction of iron and copper connected to a galvanometer cannot be used to measure temp above about 450K, whereas one of iron-constantan may be used to at least 875K. What is the explanation?

Is it possible that melting at the junction point is a limiting factor?
