(14%) Problem 7: In the figure, these three resistors are connected to a voltage source so that Ry = 5.75 Q and R3 = 11.5 2 are in parallel with one another and that combination is in series with R1 = 2.25 0. 12.0 V. R2 12 13 R * 50% Part (a) Calculate the power being dissipated by the third resistor Ry, in watts.
