Two rods of copper and iron with the same cross sectional area are joined at `S` and a steady current `i` flows through the rods as shown in the figure

Choose the most appropriate representation of charges accumulated near the junction `S`.

Three rods of same material and of equal cross sectional area and length have been connected together as shown in the figure. The temperature of the junction of the rods approximately is

Three rods of same material and having the same cross-section are joined as shown in the figure.The tremperature of junction of three rods is : .

Four rods of same material and having the same cross section and length have been joined, as shown. The temperature of the junction of four rods will be :

Three rods A, B and C of the same length and cross- sectional area are joined in series as shown. The temperature at the junction of A and B , in equilibriu, is
