Two conductors of identical dimensions of length and area of cross-section are connected in parallel. What will be their equivalent thermal conductivity?

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 bars of equal lengths and equal area of cross-section are connected in series fig. their thermal conducitives are in the ratio 2:3:4 . If at the steady state the open ends of the first and the last bars are at temperature 200^(@)C and 20^(@)C respectively, find the temperature of both the junctions. .

Three bars of equal lengths x and equal area of cross-section A are connected in series. Their thermal conductivities are in the ratio 2:4:3. If the open ends of the first and the last bars are at temperatures 200^@C and 18^@C , respectively in the steady state, calculate the temperatures of both the junctions.
