Essential Electric Circuits covers only the essential aspects of electric circuits. The fundamental aspects of DC, transient, and AC circuits are covered. Much of the excruciating detail found in traditional texts is absent. The philosophy for this is that students need to take the essential concepts with them in their careers, but they do not carry the excruciating detail with them. By excluding the excruciating detail, students will more likely retain the essential aspects they need. Includes practical workplace topics: Practical component values, the effect of tolerances, circuit loading, and real models for resistors, capacitors and inductors. Additional topics include bypass capacitors, oscilloscope probes, power dissipation in logic circuits, single supply op amp operation, and crosstalk mitigation using twisted pairs, differential signaling, and common mode chokes.
