PRACTICE PROBLEM 3.11 i1 Use PSpice to determine currents i1 , i2 , and i3 in the circuit of Fig. 3.36. 4Ω Answer: i1 = −0.4286 A, i2 = 2.286 A, i3 = 2 A. 2A i2 2Ω 1Ω i3 i1 2Ω 10 V + − Figure 3.36 For Practice Prob. 3.11. † 3.9 APPLICATIONS: DC TRANSISTOR CIRCUITS | v v Most of us deal with electronic products on a routine basis and have some experience with personal computers. A basic component for the integrated circuits found in these electronics and computers is the active, three-terminal device known as the transistor. Understanding the transistor is essential before an engineer can start an electronic circuit design. Figure 3.37 depicts various kinds of transistors commercially available. There are two basic types of transistors: bipolar junction transistors (BJTs) and field-effect transistors (FETs). Here, we consider only the BJTs, which were the first of the two and are...
