Unformatted text preview: ECE 201 Lecture 9 Mesh Analysis How to write correct loop equations • Redraw circuits, simplify them if possible; • Identify loops, sometimes they are not the obvious ones; • Determine if you use voltage drop or voltage increase. • Pay attention to the polarity of voltage drops; • Calculate the branch current carefully. Don’t lose terms at branches shared by multiple loops.
