The Positive Terminals of Two Batteries with Emf's of ₁

The positive terminals of two batteries with emf's of ₁ and 11ef181e_322b_03c7_b5ce_15ab819e17f1_TB10137_11₂, respectively, are connected together. Here 11ef181e_322b_03c7_b5ce_15ab819e17f1_TB10137_11₁ > 11ef181e_322b_03c7_b5ce_15ab819e17f1_TB10137_11_2. The circuit is completed by connecting the negative terminals. If each battery has an internal resistance of r, the rate in watts at which electrical energy is converted to chemical energy in the smaller battery is:
