proceeds as always. Kirchoff’s current and voltage laws still apply and all
of the techniques derived from those still apply. In particular, voltage
dividers, the node-voltage method, and the loop current technique are
Source transformations must be used with caution. Since the dependent
source in deﬁned in terms of a particular voltage or current, you must be
careful about changing the deﬁnitions so that the overall circuit behavior
remains unchanged. EE 442 dependent sources – 4 When using superposition, dependent sources cannot be removed. The
dependent source must stay in place for all of the partial circuits you as
consider each independent source in turn.
When doing Thevenin equivalents, you cannot remove the dependent
sources when trying to determine the equivalent resistance using the shortcut method. Thus, when dependent sources are present, the short-cut
technique become somewhat less useful.
As long as you remember those caveats for the source transformations,
superposition, and Thevenin equivalents, everything that we’ve learned to
this point can b...
