Electric Circuit Analysis/Simple Resistive Circuits/Answers

Exercise 2: Answers 600 V, 180,000W. 0.04A, more commonly written 40mA. 134.164V, 0.447A. No. There is not enough information. The only thing that is given is the voltage. With two equations there can only be two unknowns, one unknown is great, but we have three. How did you do?
