Consider a compound slab consisting of two different material having equal thickness and thermal

Consider a compound slab consisting of two different material having equal thickness and thermal conductivities `K` and `2K` respectively. The equivalent thermal conductivity of the slab is

In the question it is given that thickness of both slabs is equal and if we place them in parallel they have equal thickness 'l' . After that if we consider it in series , thn the thickness 'l' during parallel combination is going to be the length for series combination and then you can solve it by formula for series combination......it may help you... 👍

They didn't mention series?

Kese pta chala ki ye series me hai..?
