Electric Circuits provides thorough coverage of circuit analysis and circuit theory. It presents key concepts in a natural progression, helping you build on your knowledge steadily. Step-by-step analysis methods provide a solid foundation for you to develop your problem-solving skills. Over 1200 problems and nearly 200 examples introduce realistic engineering experiences that prepare you to develop the insights of a practicing engineer.
The 12th Edition includes all new assessment problems with answers. Assessment problems give you a chance to reflect on the material and test how well you know key concepts. Completely updated end-of-chapter problems offer even more opportunities for you to problem solve and practice.
This chapter analyzes circuits containing sources, resistors, and a new component, the operational amplifier (op amp). Unlike sources and resistors, the op amp is not an ideal basic circuit element. Instead, it is a complicated integrated circuit consisting of many electronic components such as transistors and diodes that are beyond the scope of this text. We can use op amps in introductory circuits, however, by taking a black box approach that focuses solely on the terminal behavior of the op amp (not on its internal structure or the currents and voltages that exist in this structure).
Operational amplifier circuits were first used as basic building blocks in analog computers. The term operational refers to op amp circuits that implement mathematical operations such as integration, differentiation, addition, sign changing, and scaling. While the range of applications has broadened beyond im plementing mathematical operations, the original name for the circuit persists.
