Question

Two metal rods 1 and 2 of same lengths have same temperature difference between their ends. Their thermal conductivities are K₁ and K₂ and cross sectional areas A₁ and A2, respectively. If the rate of heat conduction in rod 1 is four times that in rod 2, then(a) K₁A₁ = K₂A₂(b) K₁A₁ = 4K₂A₂(c) K₁A₁ = 2K₂A₂(d) 4K₁A₁ = K₂A₂
