Consider the following figure. Note: The currents are not necessarily in the direction shown. (Assume R1 = 31.0 Ω, R2 = 2.5 Ω, and V = 39 V.) A rectangular circuit begins at a battery on the bottom side labeled V with its positive terminal to the left of its negative terminal and extends leftward through resistor R2 with current I2 moving leftward. The circuit continues upward and then to the right on the top side where it splits into...
