Chapter 4 Circuit Analysis Techniques A) Node Voltage B) Mesh Current
Node Voltage and Mesh Current methods derive a minimal set of equations solve all circuit variables Node Voltage uses KCL Mesh Current uses KVL NV more powerful than MC –MC only solves "planar circuits"
Non Planar Circuit Node Voltage CAN solve, MC cannot
Node Voltage Method Basic idea—What is the current i ?
Can't write NV at v1 (current thru source?) nor V2 (same reason) SOLN: –SUPERNODE! –KCL applies to regions as well as nodes 1) Circle V1+V2 2) write KCL for Supernode 3) KVL v1, v2 and 10V Floating Voltage Source (Supernode)
