1. The problem statement, all variables and given/known data 1) Find Norton and Thevenin equivalents. 2) Use a series of Norton-Thevenin and series/parallel transformations to reduce a circuit shown into the single-loop circuit. Then, find current I. (Current I is between two nodes at the botom of (1) circuit!) 2. Relevant equations no equations 3. The attempt at a solution My way of solution is presented on these pictures. I have got two exercises which I try to solve. Thanks for help in advance!
