Circuit Analysis What is it good for? For a given circuit a) Find node voltages and branch currents, or b) Find component values resulting in desired node voltages and branch currents design EE 40 Lecture 6: Circuit Analysis 2
Circuit Analysis What are the techniques? General approach (any circuit): KVL, KCL Component equations (e.g. Ohm’s law) Special techniques: Series & parallel connections Dividers Source transform EE 40 Lecture 6: Circuit Analysis 3

Circuit Analysis with KVL, KCL Nodes: n = Branches: b = # KCL equations: # KVL branches: # Unknowns: EE 40 Lecture 6: Circuit Analysis 4 6 10 n-1 Node voltages (infer branch currents from node voltages and elements)
Problem Many more KVL, KCL equations than unknowns Which ones should we use? Node voltage analysis (NVA)
