Below is a circuit with 3 batteries and 2 resistors. Depending on the voltages of the batteries and the values of the resistors, either 1 or 2 of the batteries may be getting charged by the circuit. At least 1 battery has to be providing power to the circuit. But without solving Kirchhoff's Junction Rule and Kirchhoff's Loop Rule you don't know which is which. To determine which category the batteries fall into, you need to determine the magnitude and direction of the current in each leg of the circuit. The image below has the guessed direction of current, which is not necessarily correct. But you can use this to start your problem solving. The values for the resistances and batteries are below. R, C + E1 E2 E3 R2 R1 = 73.0 Ohms R2 = 66.0 Ohms E 1 = 8.40 V E 2 = 4.40 V E 3 = 12.79 V Find current iz in this circuit. Indicate direction by putting a - sign in front of the number if the actual current is traveling the opposite direction of the diagram. If the current is the same direction as the diagram, then you can just enter the answer (you can't enter a + sign). Make sure to give your answer in appropriate significant figures and also include units. You should use the letter (don't spell out the unit in this case). Your Answer: Answer units
