For an example, imagine where the medical field would be without electricity and in that sense how many lives have been saved due to electrical devices like defibrillators, pacemakers, etc.
Read on to discover more about basic electrical theory. What is Electricity?
So what is electricity and where does it come from? More importantly, why is carpet, socks and a doorknob a bad combination? In its simplest terms, electricity is the movement of charge, which is considered by convention to be, from positive to negative.
No matter how the charge is created, chemically like in batteries or physically friction from socks and carpet , the movement of the discharge is electricity. Understanding Current This flow of electrical charge is referred to as electric current. There are two types of current, direct current DC and alternating current AC. DC is current that flows in one direction with a constant voltage polarity while AC is current that changes direction periodically along with its voltage polarity.
But as societies grew the use of DC over long transmission distances became too inefficient. Nikola Tesla changed all that with the invention of alternating current electrical systems. With AC it is possible to produce the high voltages needed for long transmissions.
Therefore today, most portable devices use DC power while power plants produce AC. The V is for voltage, which means the potential difference between two charges. In other words, it is a measurement of the work required to move a unit charge between two points.
When we see a value such as 10 Volts, it is a measurement of the potential difference between two reference points. As mentioned previously, current is the measurement of the flow of charge in a circuit. This leaves us with the letter R which represents Resistance.
Lessons in Electric Circuits
Electrical resistance, measured in Ohms, is the measure of the amount of current repulsion in a circuit. Simply, resistance resists current flow.
When electrons flow against the opposition offered by resistance in the circuit, friction occurs and heat is produced. The most common application for resistance in a circuit is the light bulb.
The light bulb introduces enough resistance in a circuit to heat up the filament inside, causing light to be emitted. Resistance in a circuit can also be helpful when needing to alter voltage levels, current paths, etc. Resistors are self-contained packages of resistance that can be added to a circuit and are commonly used to divide voltage levels. First, we need to understand what Series and Parallel circuits mean.
Series circuits are those which are connected in-line with the power source.
The current in series circuits is constant throughout but the voltage may vary. Parallel circuits are those which branch off from the power supply.
The total current supplied from the power source is divided among each of the branches but voltage is common throughout. You have probably experienced the pain involved with installing Christmas lights only to realize none of them work. Cue Clark Griswold! There is probably one bulb out somewhere in the hundreds that you hung up. More than likely it is because one of the lights decided to break or burn out and because they are wired in series the rest are now out as well.
Since all of the lights are in-line with each other, if one goes out it causes an open circuit at that point. No current will flow to the other lights because of the open circuit path. The book is recommended for those who study electronics. This ebook makes learning "complex" numbers easy through an interactive, fun and personalized approach.

Features include: The book contains problems with worked solutions, called examples, and some additional problems for which the answers only are given. This book explains how AC sources are generated and analysed.
It shows how these systems can be analysed without the use of advanced mathematics, and supplements prescribed textbooks on this subject. The book covers the basic aspects of linear single loop feedback control theory. The book defines the units of electrical quantities from first principles. This book takes learning to a new level by combining written notes with online video.
Each lesson is linked with a YouTube video from award-winning teacher and best-selling author Dr Chris Tisdell. Partial differential equations form tools for modelling, predicting and understanding our world. Power Electronics is the technology associated with efficient conversion, control and conditioning of electric power from its available input into the desired electrical output form. As marching into the digital era, many people in different sectors are quite keen to understand why this has happened.
This is a companion volume to Electromagnetism for Electronic Engineers 3rd edn. This book is intended primarily for the secondary-level and university-level learners of an electromechanical profile. This introduction to electromagnetic theory emphasises on applications in electronic engineering. This book is intended primarily for the university-level learners of an electromechanical profile, including the bachelor and master students majored in electrical engineering and mechatronics.
The presented work describes an electric, magnetic and thermal analysis of a synchronous motor to permanent magnet and intended axial flux to cooling. HVAC systems play a critical role in maintaining the indoor environment which has a direct impact on the h. Essential Electromagnetism provides a concise introduction to this fundamental topic.
Starting with forces on charges, it takes a logical step-by-step progression through electrostatics and magnetost. Learn calculus on your mobile device!Supplemented with three appendices addressing matrix algebra, trigonometric identities and Laplace transforms of commonly used functions to help students understand the mathematical concepts required for the study of electrical engineering. Finally, the book includes a discussion on technologies of electric power generation along with the different types of energy sources.
The supply voltage was divided among the loads in proportion to the resistance each load carries. I was taught to think that current flows much the same as water.
The book also presents the analysis of ac circuits, and discusses transient analysis due to switch operations in ac and dc circuits as well as analysis of three-phase circuits. And, in this case, we decided to sweeten the deal and scour the internet for the most reputable, reliable sources of information on electrical engineering that just so happen to be free.
The book, made up of five chapters, systematically covers the five units of the syllabus. Provides well-graded chapter-end problems to develop the problem-solving capability of the students.
Part II is concerned with elastic stress analysis problems of the plane strain and plane stress types. Showing 36 results View as list or grid Sort by popularity rating published.
