ABSTRACT

By using Kirchhoff’s laws, mesh-current analysis, nodal analysis or the superposition theorem, currents and voltages in many networks can be determined as shown in Chapters 30 to 32. Thévenin’s and Norton’s theorems, introduced in Chapter 33, provide an alternative method of solving networks and often with considerably reduced numerical calculations. Also, these latter theorems are especially useful when only the current in a particular branch of a complicated network is required. Delta-star and star-delta transformations may be applied in certain types of circuit to simplify them before application of circuit theorems.
