A power supply has an open-circuit voltage of 40.0 V and internal resistance of 2.00 Ω. It is used to charge two storage batteries connected in series, each having an emf of 6.00V and internal resistance of 0.300 Ω. If charging current is to be 4.00A, (a) What additional resistance should be added in series. At what rate does the internal energy increase in (b) the supply, (c) in the batteries, and (d) in the added series resistance? (e) At what rate does the chemical increase in the batteries?
