Slide 4 EE40 Fall 08 Connie Chang-Hasnain Dependent Sources • Treat each dependent source (of any of the four kinds) as a new variable, associated to a ``known” source and proceed as before using nodal analysis. • At the end, you get an extra equation from the dependency that defines the source, for each dependent source. • These extra equations will allow you to complete the solution. – Dependent sources cannot be turned off for various purposes ( e.g. to find the Thévenin resistance, or in analysis using Superposition).
