Solve the circuit by finding the values of all the currents. 2 Ω mi M In this assignment you will be following the problem solving strategy for Kirchhoff Rules. 1. Reproduce, as neatly as possible, on paper, the circuit shown above. Do not make the circuit too small as you will have to add things to it later. 2. Label all relevant points in this circuit. For your benefit these points are marked with dots in the Figure above and they include: circuits junctions (i.e. places where 3/more wires connect), wire "corners" (i.e. places where a single wire is bent), and locations between two components on a single straight wire. These will help identify loops as well as making it easier to keep track of potential differences. Use lower case letters (a, b, c, ...) for this task. 3.
