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

Two rods A and B of same length and cross-sectional area are connected in series and a temperature difference of 100^@C is maintained across the combination as shoen in Fig. If the thermal conductivity of the rod A is 3 k and that of rod B is k, Then i.Determine the thermal resistance of each rod. ii. determine the heat current flowing through each rod. iii. determine the heat current flowing through each rod. iv. plot the variation of temperature along the length of the rod.

Three metal rod A, B and C of same length and cross-section are placed end to end and a temperature difference is maintained between the free ends of A and C. If the thermal conductivity of B(K_B) is twice that of C(K_C) and half that of A(K_A) , then the effective thermal conductivity of the system will be

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 made of the same materail and having same cross-section area but diferent length 10 cm, 20 cm and 30 cm are joined as shown. The temperature of the junction is

Three rods each of same length and cross - section are joined in series. The thermal conductivity of the materials are K, 2K and 3K respectively. If one end is kept at 200^@C and the other at 100^@C . What would be the temperature of the junctions in the steady state? Assume that no heat is lost due to radiation from the sides of the rods.

Two conducting rods A and B of same length and cross-sectional area are connected (i) In series (ii) In parallel as shown. In both combination a temperature difference of 100° C is maintained. If thermal conductivity of A is 3 K and that of B is K then the ratio of heat current flowing in parallel combination to that flowing in series combination is

Three rods of the same length and the same area of the cross-section are joined. The temperature of two ends one T_(1) and T_(2) as shown in the figure. As we move along the rod the variation of temperature are as shown in the following [Rods are insulated from the surrounding except at the faces]

Three rods AB,BC and BD made of the same materical and having the same area of cross section have been joined as shown is the The ends A,C and D are held at temperatures 20^(@)C Cand 80^(@)C respectively If each rod is of same length then find the temperature at the junction B of the three rods .
