The Positive Terminals of Two Batteries with Emf's of ε1

Question 50

Multiple Choice

The positive terminals of two batteries with emf's of ε1 and ε2, respectively, are connected together. Here ε1 > ε2. 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:
