Simplifying Circuit Analysis with Source Transformation and Division Techniques

In This Chapter

Recognizing equivalent circuits

Transforming circuits into equivalent series and parallel circuits

Analyzing circuits with voltage and current divider techniques

Using Kirchhoff’s laws and Ohm’s laws (see Chapter 3) can get pretty laborious when you’re analyzing complex circuits. Fortunately, you can make analyzing circuits easier by replacing part of the circuit with a simpler but equivalent circuit.

Through a makeover or transformation technique, you modify a complex circuit so that in the transformed circuit, the devices are all connected in series or in parallel. After the transformation, you no longer need to systematically apply Kirchhoff’s laws, because you can use shortcuts: the current divider technique and the voltage divider technique.

In this chapter, I explain how to make the transformation and apply both types of divider techniques. Rest assured that the info in this chapter can make your life a little easier when you start analyzing more-complex circuits.
