Vo 13. There are four identical resistors each in cylindrical shape. Their curved surfaces are thermally insulated therefore heat transfer can take place through their circular ends only. When one of them is connected across an ideal battery, its steady state temperature becomes O = 38 °C. Now the remaining three resistors are connected in series with very good electrical contacts and the pack is connected across the same battery. To what value will the temperature of this pack rise in steady state? Room temperature is 0 = 20 °C and amount of heat transfer to the surroundings is proportional to the temperature difference between the resistor and the surroundings. Neglect thermal expansion and change in resistivity for the range of temperature involved. %3D %3D Iu innulated from the surroundings is divided into
