Method:

1. Calculate electrical resistance of wire base on either (resistivity * length) / cross-sectional area or from tables.

2. Use required current and resistance according to (i^2)*R to calculate power dissipation

3. Calculate thermal resistance according to length / (thermal conductance * cross sectional area)

4. Calculate thermal rise according by power 8 thermal resistance

Thanks in advance...
