Does Resistance change wrt temperature include effect of size change

[QUOTE="berkeman, post: 6539691, member: 8921"] Okay, nothing definitive yet in my searching, but it definitely looks like anybody measuring resistivity to any fine accuracy would want to be sure to use the dimensions of the sample at the temperature measured during the test. And since you don't need to use a large current to measure the resistance of the sample, the temperature increase of the sample due to the test current may be very small...
