Question:

In the circuit shown in Fig, the rate at which R1 is dissipating electrical energy is 20.0 W.
(a) Find R1 and R2.
(b) What is the emf of the battery?
(c) Find the current through both R2 and the 10.0-Ω resistor.
(d) Calculate the total electrical power consumption in all the resistors and the electrical power delivered by the battery. Show that your results are consistent with conservation of energy.
