| Copper wire resistance - RF Cafe Forums | ||||||
|
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. 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. Posted 11/12/2012 | ||||||
