Consider the circuit of Fig. E25.30. (a) What is the total rate at which electrical energy is dissipated in the 5.0- Ω and 9.0- Ω resistors? (b) What is the power output of the 16.0-V battery? (c) At what rate is electrical energy being converted to other forms in the 8.0-V battery? (d) Show that the power output of the 16.0-V battery equals the overall rate of consumption of electrical energy in the rest of the circuit.
