AC Network Theorem

This chapter will parallel Chapter 8, which dealt with network theorems as applied to dc networks. It would be time well spent to review each theorem in Chapter 8 before beginning this chapter because many of the comments offered there will not be repeated. Due to the need for developing confidence in the application of the various theorems to networks with controlled (dependent) sources, some sections have been divided into two parts: independent sources and dependent sources. Theorems to be considered in detail include the superposition theorem, Thevenin's and Norton's theorems, and the maximum power theorem. The substitution and reciprocity theorems and Millman's theorem are not discussed in detail here because a review of Chapter 8 will enable you to apply them to sinusoidal ac networks with little difficulty.
