@1.21Gigawatts - thank you! This is precisely what I was looking for. I have been traveling, so my apologies for the late response.
The applications we get into typically are AC, not DC. I wonder if that will change the equation, or if since the current is symmetrical, the AC has a net zero effect?
With regards to your note about unevenness - absolutely. The material certainly isn't perfect, not to mention that they two legs have a symmetry tolerance. At high currents, I would have to believe that this makes a difference.
On a side note, what do you do for a living? I run across very few people who know MoSi2. We have been working with Kanthal for over a decade in a FAE/ sales capacity. Not too many folks outside of industrial heating are even aware of what we do
@ChrisGammell - I am glad you started this forum!
