A wall has two layers A and B made of different materials The thickness of both the layers is the same The thermal conductivity of A and B are KA and KB such that KA 3KB The temperature across the wall is 20 C In thermal equilibrium MP PET 1996 99 BHU 1997 CPMT 1998 DPMT 2000 RPMT 2005 Kerala PET 2012 The temperature difference across A 15 C The temperature difference across A 5 C The temperature difference across A is 10 C The rate of transfer of heat through A is more than that through B
