Consider the circuit of Fig.
(a) What is the total rate at which electrical energy is dissipated in the 5.00-Ω and 9.00- 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 dissipation of electrical energy in the rest of the circuit.
