- Calculate the range of possible values for each resistor.Kirchhoff Loop Problem 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.
