Hi everyone!This course is designed to provide a complete understanding of electric circuits starting from the basics and fundamentals of electrical engineering moving to advanced topics in electric circuits for complete beginners without any previous knowledge.Electric circuits analysis is the fundamental theory upon which all branches of electrical engineering are built. Many branches of electrical engineering, such as power engineering, electric machines, control, electronics, communications, and instrumentation, are based on electric circuit theory. The course is roughly divided into the following topics: >What is an electric circuit?System of Units & SI PrefixesDefinitions of electric charge, current, voltage, power and energyBasic circuit elements and their applicationsDC current vs. AC currentDifference between independent and dependent sourcesPower balance in electric circuits >Ohm's law in electric circuitsVarious properties of resistorsKirchhoff's current law (KCL) and Kirchhoff's voltage law (KVL)Short circuit and open circuit Circuit reduction topology using series and parallel resistorsVoltage and current divider rulesStar and delta connections Star to Delta transformation and vice versa for the circuit reductionNodal analysis method and concept of super nodeElectric circuit applications as lighting systems >The concept of linearity and linear circuitsDifferent electric circuit theorems such as superposition and source transformation theoremsThevenin theorem in electric circuitsHow to apply Thevenin with dependent sources?The maximum power transfer theory using TheveninNorton theorem in electric circuits >Various properties for capacitors and inductorsThe voltage and current relations in capacitors and inductorsThe energy stored in capacitors and inductorsHow to simplify capacitive, and inductive circuits?Series and parallel capacitors and inductors >Basics of operational amplifiers (Op-Amps)Difference between ideal and practical Op-AmpsDifferent types of Op-Amps such as inverting, non inverting, summing and difference amplifiersDifferent applications on Op-Amps such as differentiator, integrator, cascaded Op-AmpsHow to implement digital to analog converter (DAC) using Op-Amps?How to build instrumentation amplifier (IA) using Op-Amp circuits? >First order DC transient circuitsForced and free response of R-L circuitForced and free response of R-C circuitThe key to working with any R-L or R-C circuitsThe analysis of second order DC transient circuitsAnalysis of series RLC circuitDifferent responses for RLC circuitHow to analyze any general RLC circuit? >Practical difference between AC and DC circuitsAC sinusoidal sources and phasorsIdentify the phasor representation for AC sourcesV-I relations for resistors, inductors and capacitors in AC circuitsDefinitions of impedance and admittanceApply different circuit techniques and theorems in AC circuitsApply KVL, KCL, impedance combinations, mesh and nodal techniques in AC circuitsApply superposition, source transformation, Thevenin and Norton theorems in AC circuitsRealize Cramer's rule and the elimination technique in analyzing any AC electric circuitAnalysis of Op Amp AC circuits >Practical importance of AC power analysisDifference between instantaneous and average powerApply maximum power transfer theory in AC circuitsThe root-mean-square (RMS) value and its importance in AC circuitsIdentify the apparent power (S) and power factor (PF)Discuss the complex power and its importance in AC power analysisDifference between active power (P) and reactive power (Q)Realize the power triangle in relating the different types of AC powerRealize the consequences of low power factor in AC power systemThe role of capacitors in improving the power factor >The advantages of using 3-ph systemsThe origin of balanced three phase supplyStudy different possible connections in balanced 3-ph circuitsApply (star-star), (star-delta), (delta-star), (delta-delta) 3-ph connectionsDiscuss the difference between (3-wire) and (4-wire) 3-ph systemsThe difference between line and phase voltagesThe relations between line and phase currentsHow to analyze unbalanced star or delta loads in any 3-ph system >Power calculations in balanced 3-ph systemPower calculations in unbalanced 3-ph systemHow to calculate the power losses in any 3-ph system?How to improve the power factor in 3-ph circuits? >Realize the electric resonance phenomena in electric circuitsSeries resonance vs. parallel resonanceProperties of resonant circuitsHalf power frequencies in resonant circuitsBandwidth and quality factor for electric resonanceApplications of resonance circuitsDrawbacks of unwanted resonance You will find several solved examples and practical applications to illustrate the analysis of practical circuits By the end of this course, you will be able to start your career in electrical engineering, power and computer engineering and electronics so that you will be able to analyze different electric circuits from basics to advanced I thank you very much for taking the time to check the course content.
