I am trying to teach myself electronics. I am currently reading/studying a book Complete Electronics Self-Teaching Guide. I am getting stuck on a bunch of Ohm's law questions, one of which says Vs = 12 Volts, I = 300mA, R1 =50 Ohms. It is in a parallel circuit with Vs, I, R1, R2, and I1, I2. I thought I would have divided 12 Volts by 300 mA I get 40. The answer in the book says that R2 should be 200 Ohms and P1 2.88 Watts. I can't seem to get these answers. Can someone help me out. Thank You in advance.
