Most of the examples dealt with so far, and particularly those utilizing batteries, have constant voltage sources. Once the current is established, it is thus also a constant.

Course Assessment Standards. This is an introductory course, and as such, it assumes that you know very little about electricity. No previous course work in electricity or electronics is required. Basic electrical concepts such as voltage, current, power, and resistance are introduced and examined for DC direct current and AC alternating current. Fundamental laws and relationships such as Ohm's law and power law are developed.

Analysis techniques include series-parallel simplification; Thevenin's, Norton's, and superposition theorems; and mesh and nodal analysis. A good scientific calculator with simultaneous equation solution capability will be of great use and is strongly recommended. Further, smart devices will not be allowed during tests. Late penalty is one letter grade for the first half week, two letter grades for the second half week. Reports are not accepted beyond two weeks and receive a grade of 0.

Remember, plagiarism is grounds for failure. An on-line resource covering a variety of electrical circuit topics and reference material may be found at: www. Week-by-week progress and assignments note that the problems are found in the OER texts , not the Nilsson text, unless stated otherwise.

We define voltage and current sources, both independent and dependent. We continue with the interrelationships and examine parallel and series-parallel networks for the DC case.

We finish our discussion of basic series-parallel networks for the DC case and introduce the concept of source conversions. We continue with network analysis including superposition. We also introduce Thevenin's theorem and maximum power transfer theorem. We finish our work involving the analysis of resistive DC circuits.

At this point, we will have our midterm test. We continue our discussion of inductors and capacitors, and investigate the natural and step responses. We begin with a review of complex numbers and consider polar, rectangular and exponential formats. We introduce the concept of phasors. We introduce steady state sinusoidal excitation of RLC circuits.

When this is completed, we will have our second test. We continue steady state sinusoidal excitation of RLC circuits. This includes the power triangle, power factor and maximum power transfer for the AC case. We examine sinusoidal steady state power calculations including instantaneous power, RMS value, "complex" power, and the like. Topics include electrical laws, quantities, and DC and AC circuits. We begin with an introduction to electrical quantities such as charge, current, voltage, power, resistance, conductance and impedance.

Understanding DC Circuits By Dale R Patrick and Stephen W Fardo

Publisher: University of Oklahoma Libraries. This text book covers the basics of DC circuit analysis. It could be considered as a valuable reference book. However, I would not consider it as a text book as it lacks problems. The links provided in the book would make this book a true Comprehensiveness rating: 3 see less. The links provided in the book would make this book a true electronic book.

Since most circuits and basically all body electrical circuits work on. In ac circuits, the SCR can be turned on by the gate at any angle a with respect to the applied voltage. Find the equivalent resistance between terminals A and D, which then can be used to calculate the source current for a given supply voltage. Established in , it has a membership of around 50, members worldwide. Objective of this laboratory manual is to teach students about electronics components, characteristics of semi-conductor devices and design rectifiers, filters and amplifiers, simple electronic circuits.

The major difference between the AC and DC voltage is that in AC voltage the polarity of the wave changes with the time whereas the polarity of the DC voltage always remains same. The other differences between the AC and DC voltage are shown below in the comparison chart. The voltage which causes the alternating current is known as the AC voltage. The alternating current induces in the coil when the current carrying conductor rotates in the magnetic field. The conductor when rotates cuts the magnetic flux and the variation of the flux induces the alternating voltage in the conductor. The dc voltages induce the direct current. The generation of the DC voltage is quite simple and easy.

The handbook includes information on alternating current (AC) and direct current (DC) theory, circuits, motors, and generators; AC power and reactive components​.

Over the course of the next few chapters, you will learn that AC circuit measurements and calculations can get very complicated due to the complex nature of alternating current in circuits with inductance and capacitance. AC circuit calculations for resistive circuits are the same as for DC. With purely resistive circuits, however, these complexities of AC are of no practical consequence, and so we can treat the numbers as though we were dealing with simple DC quantities. One major caveat needs to be given here: all measurements of AC voltage and current must be expressed in the same terms peak, peak-to-peak, average, or RMS. If the source voltage is given in peak AC volts, then all currents and voltages subsequently calculated are cast in terms of peak units. Unless otherwise stated, all values of voltage and current in AC circuits are generally assumed to be RMS rather than peak, average, or peak-to-peak.

Сьюзан от изумления застыла с открытым ртом. Она посмотрела на часы, потом на Стратмора. - Все еще не взломан.

Он подумал о Сьюзан. Но тут же в голову пришли слова Стратмора: Найдите кольцо.
