Kent Post subject: Copper wire resistance Unread postPosted:
Thu Dec 23, 2004 11:10 am We are working on a new electronic
sensor device which requires the periodic measurement of a 28AWG
kynar insulated copper wire loop (ten feet long) under varying ambient
temperatures. Since the electrical resisitivity of copper increases
linearly with the ambient temperature, we know the following facts
about copper wire at a temperature of 20C: 10.09 (ohm-cmil/ft)
1.678 (micro-ohm-cm) Our problem is that we need to know
the electrical resisitivity of copper wire at each degree reading
between -20C and +70C ( in addition to the electrical resisitivity
we know that copper has at 20C). If anyone has a suggestion or
reference for further information, please advise as soon as possible.
Thanks in advance for your help in this matter.
