A current of 10A passes through the electric wire and there is a voltage drop of 8V along the wire. The diameter of the wire is 3mm and the length is 12m. The wire is wrapped with a 1.5-mm-thick cover whose thermal conductivity is k = 0.15 W/m·°C. If the insulated wire is exposed to calm atmospheric air at ?∞ =30°C, determine the temperature at the interface of the wire and the plastic cover.
