Current Handling - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Can anyone tell me the equation to figure out how much DC current I can carry on a transmission line given the line's width, thickness, and conductivity? Thanks.
