A current of 200 A is passed through a stainless-steel wire [k=19 W/mK] 3 mm in diameter. The resistance of the steel may be taken as 0.099 ohm, and the length of the wire is 1 m. The wire is submerged in a liquid at 110 C and experiences a convection heat-transfer coefficient of 4 kW/m?K. Calculate the center and surface temperatures of the wire. Resistance heater
