I'm not sure if this question belongs in the forum or the physics forum, I guess I'll post it there as well. I'm trying to calculate the temperature rise in a coil of wire (27AWG) wound around a toroid. The current through the wire is ~0.5A with a calculated voltage drop of 14.64mV across the 18" wire due to the wire resistance. The ambient temperature of the wire is 125C. The wire insulation max temp is ~220C. I'm interested in calculating the temperature rise in the wire. How would I go about this?(adsbygoogle = window.adsbygoogle || []).push({});

Background info: This design is for a switching power supply, 28V to 5V, isolated, Fs=250khz, Tambient=125C.

Thanks for any insight.
