Relation between current and temperature in metals...

[subbuindia]

What is the formula that shows the relation between temperature and current in metals?

Are you talking about resistive heating? https://en.wikipedia.org/wiki/Joule_heating

For metal interconnect ratings, electromigration lifetime goes as inverse
exponential of temperature. However the exponent fitting terms vary a
lot with metallurgy. See "Arrhenius equation". Then accept that you don't
know anything useful without a well-carried-out experimental result, on
somebody's part.
