An insulated copper wire with a length of 1.2 m carries 20 A of current. The copper is 1 mm in diameter and the insulation (k=0.13 W/m. ºC) has a thickness of 0.8 cm. The wire has electrical resistance of 0.0321 Ω. Air at 25 ºC blows in crossflow over the wire to produce an external convective heat transfer coefficient of 219 W/m2. K. Assuming the copper is isothermal, find the copper temperature. Take the electrical resistivity of copper to...
