***** Feedback from Students *******
"I love this course. It truly is an amazing subject and the instructor gives great explanations on how electronics works. It amazes me how electronics are used every day and most people have no clue as to how they work." Joseph C.
"Excellent coverage of the fundamentals. Thanks!", Kevin O'Reilly.
"For years I have wanted someone to explain the basics of electronics to me, and this course does just that, in clear, small focused chapters. I really recommend this to anyone that wants to learn the fundamentals of electronics." Paul Cockrell.
"This is fantastic. So well organized and presented so clearly! I feel like I'm learning very quickly. I even understand voltage and amperage which other people have explained to me many times but I never "got" without a visual analogy. Thank you for this wonderful class, I highly recommend it!." Cjay Roughgarden.
"Excellent course for beginners and intermediate electronics. I am in my first year of EET in college and this has been a great supplement to my initial courses. I hope you put out some more advanced Electronics courses later on. You do an excellent job of putting everything into terms that are relatable. Thanks" David M.
Electricity is all around us, it is some hidden energy force driving many applications we all use in our daily life. The theory behind electricity is based on some amazing phenomenon in nature and some of several materials properties that were discovered by great scientists. Electronics is a theory developed around the useful applications of electricity. So, the first thing that we can say about electricity is that it is a really interesting subject!
Today, electronic is becoming much more friendly hobby for many people worldwide that would like to easily combine hardware and software and do things by themselves, the prices of electric components are dropping, easy to use development platforms were created (e.g. Arduino) and it is very easy to collaborate and learn the subject in a few mouse clicks.
The Internet of Things is also an emerging driving force for innovators looking to build things using electronics and harness the power horse of the web technologies to create new products, services or just cool projects!
This course is a starting point, to learn the basic building blocks of electronics with step by step education program, easy to follow chapters, simple circuits’ demonstrations, quizzes to evaluate your understanding and review the key things to remember using a mind mapping template.

Starting with a short course introduction on Why ? What ? How ? Who ?....
Atoms (OMG!) are the building blocks of materials around use, Electric Charge is the amazing property of electrons and protons inside each atoms. Did you know that electric charge is holding the all universe from falling parts...... I am not kidding....
OK, but what is the relation to Current ?
Power is the rate of energy being consumed in specific component and it is based on the amount of voltage drop and current flowing in that component. Power is measured using watts. To measure power consumption we need to add the time scale so in that case, power consumption is measured using Watts-Hours. In addition, to measure the energy capacity of some limited energy source like a battery we use Amperes-Hours.
Resistance is the property of a material, measured in ohms. What happens when some material resist to current flow ? "I think it is getting HOT in here..."
Capacitors are widely used as parts of electrical circuits:
Blocking direct current while allowing alternating current to pass
Smooth current fluctuations for signal or control circuits
Filter specific frequencies (e.g. radio)
Generate signal waves used for timing
And more….so commonly used that in almost every circuit we will find them pushing their big nose...
Electromagnetism = Electro + Magnetism
Magnets?!? , what are you talking about ?
Not easy but really interesting stuff !
Time-varying magnetic field (flux) induces an electromotive force in nearby conductors. The induced force is called Electromotive Force (EMF). A device specifically designed to produce the effect of mutual inductance between two or more coils is called a transformer. All our AC to DC converters are working based on this effect.
Materials are classified by their ability to conduct electricity. Substances that easily pass an electric current, are referred to as conductors. Materials that have a difficult time passing an electric current are called insulators. A third category of material whose conductivity lies between those of conductors
and insulators. This third category of material is referred to as a semiconductor.
Ohm’s Law and Kirchhoff's Laws are the basic laws of electric circuits helping to perform simple to complex circuit analysis.
