A major advantage of analyzing circuits using Kirchhoff's laws as we did
in previous chapters is that we can analyze a circuit without tampering with its
original configuration. A major disadvantage of this approach is that, for
a large, complex circuit, tedious computation is involved.
The growth in areas of application of electric circuits has led to an
evolution from simple to complex circuits. To handle the complexity,
engineers over the years have developed some theorems to simplify circuit
analysis. Such theorems include Thevenin's and Norton's theorems.
Since these theorems are applicable to linear circuits, we first discuss the
concept of circuit linearity. In addition to circuit theorems, we discuss the
concepts of superposition, and maximum power
transfer in this chapter. The concepts we develop are applied in the last
section to source modeling and resistance measurement.
