I am currently working at a company which make electrical underwater connectors. Recently I have been given a project where I have to carry out some theoretical tests on connector conductors. One test is puzzling me though. The test in question is: When the conductor temperature increases from ambient 35 degrees celcius to 140 degrees celcius, how does this effect to resistance. i.e. A current of 50A has to be maintained when the temperature of the conductors reach 140c.
Now, I would of thought to use a resistance temp equation (R = R0 [1 + a(T-T0)]) but I have been vaguly told of an equation similar to (R = I^2 * T) -which almost looks like a power equation- I have never come across this equation....does anyone know what this guy wants? (It could be an american thing, as the comapny wanting me to do this report are based there, and I am in the UK)
Thanks
