In a few of my undergraduate lab sessions, we have been given a formula in the lab script;
[tex]\[R=R_{20}(1+\alpha T+\beta T^{2})\][/tex]
Where Alpha and Beta have varied depending on the experiment.For example, to calculate the temperature of a cathode, at resitance R, [tex]\[\alpha \][/tex] was 5.24x10-3 and [tex]\[\beta\][/tex] was 7x10-7 (this was in degrees).
What actually is this equation? I'm curious to see where it's come from.
