In order to understand what electronics is, you need to have a basic understanding of what electrons are, since the entire study revolves around these tiny particles of matter. Without going too deep into the physics of electrons, it is sufficient to say that electrons are negatively charged particles found in every single atom in existence. They act as carriers of electricity and it would not be possible to get an electrical current from point A to point B in any solid without electrons. These particles are so small that the science that goes into studying them must be as precise as the resulting application of what has been learned. Electronics deals with all of that.
Over the past few decades, a growing understanding of how electrons work has led to many inventions, a large portion of which we take for granted in everyday use. This is because electronics deals with how electrons affect different environments. Understanding how to manipulate the reactions that occur when electrons are put through different mediums and under different conditions allows for the ability to create different inventions.

There are a number of appliances that can give good examples of how electronics is applied and the benefits wrought from such application. In order to narrow down all of what has been accomplished, finding an example of something everyone can use is helpful, and a radio is one such exemplary instrument. The circuit found within the radio serves as a map for electrons to travel through. This channeling process is simple, in principle, but it results in the rather complex and impressive ability to transmit and receive voices and sounds in a way that otherwise would not be possible. The ability to manipulate electrons in this way, among many other ways, is what makes electronics one of the most important studies to further contemporary technology and advance human civilization.
Essentially, what is taught in electronics is how to build circuits, but that statement alone isn’t a good enough description of the foundations of the science. A more detailed analysis is needed, divided into distinguished categories, each of which summarizes the different areas explored in electronics.
Addressing the issue of where current and voltage comes from is a good place start. An understanding of how everything flows is necessary before getting into circuitry, which is basically the creation of pathways, gates, and storage houses. Understanding the source of energy is as important as the nature of energy being channeled. Following this, conductors come into play, starting off the guiding process which electrons follow throughout a circuitry. Insulators also help with the guiding process by limiting amounts to prevent an overflow. All this is just the beginning of what can turn out to either be a very long and sophisticated circuit that yields an impressive end result, or it could be the start of a simple circuit that results in the function of a simple mechanism. In either case, understanding current and voltage is the beginning of everything in electronics, including the learning process.
A good understanding of AC is a necessary requirement when learning electronics. While DC deals with a flow of electric current heading in one direction only, AC is less straightforward, and so it deserves special attention. It is also a good example of a type of current that is not usually ideal when it comes to getting circuits to work. There are solutions for this which we will get into later. It is important to know that there are different types of AC waveforms that are common when dealing with electronics. Understanding these, along with the frequency of their waves, is essential in being able to get electrons to work for you. The voltages that occur in a waveform is something also studied with the aid of the aforementioned understanding of energy flow in general.
Not all current is suitable for channeling, especially if you are aiming for a certain result when building a circuit in which to channel electrons. Transformers are necessary inclusions in a circuit for transforming voltages such as AC voltage. They work to either increase or decrease voltage values according to what is specified by whoever is building the circuit. These usually fit right in the middle of the pathway electrons take. Current and channeling are needed before a transformer can be put to use, and after it either changes or transforms voltage, the current is then better able to function in useful ways.
As was previously stated, electronics is all about the management of electrons, using them to work in a number of different ways. This is the heart of circuit building, and while all elements that are included do actually help with the management process, resistors are key to the whole management process. While most other components of a circuit facilitate the flow of electrons, resistors do the opposite, as their name suggests. They work to strategically stop the flow of electrons in calculated measures. This isn’t to interrupt a circuit’s function, rather, it works to the opposite effect. Being able to stop a flow of current at will gives one the further flexibility to create a number of different devices that work in different ways. There are two different values that are covered when learning electronics. Also part of this is the ability to measure resistance, in ohm values, which is essential in making accurate calculations.
There is a state in which electrons are neither permitted to flow nor sent back. At such times, they can be stored in a particular location until such a time arises when they are needed. Capacitors act as such storage places in a circuit. There are a number of different types of capacitors, made from different materials, though the typical capacitor is made from a metal plate or foil. The differences between the different makes are important to understand, as they determine how much can be stored; some materials simply work as better insulators than others. The amount of electric charge stored is referred to as capacitance. The ability to measure capacitance and the impact it has on how much voltage is permitted is just another important lesson to be learned when studying electronics. Like other components, it also invites the possibility for many different types of circuit builds, each resulting in a unique function.
The magic of magnetism comes to life when electrons clash together to create a powerful force that is naked to the invisible eye. The effects of this attractive force, however, are anything but invisible. Since electronics is the study of electrons, it is only natural that some mention of magnetism comes up when studying the science. More importantly, the way electrons react within a circuit can have numerous effects resulting in reactions that can be beneficial. Coil wires are the components used in such an operation. When a magnetic field encounters one such coil wire, a voltage is then created in that coil, a reaction that is called induction. Knowing how induction works is one of the key foundations of learning electronics and being able to use the science to create and innovate.
As should have been made apparent by now, the nature of different materials generates different results, all of which are studied in electronics and used when building circuits. Some components, however, feature qualities that can be found in two different components. Semiconductors are a good example since these have properties that are in between that of a conductor and that of an insulator. To the many resourceful and creative minds, this can and is often used to one’s benefit, making them a necessary inclusion in the study of semiconductors. Transistors and diodes are examples of different types of semiconductors that are used. They are also made from different materials, though silicon is the most popular on account of its particular semiconducting properties.
Ultimately, all the aforementioned components are useless unless they are put together. Even then, the combination in which they are put together has to be carefully thought through and calculated if anything useful is to come of it all. When combining two or more of the many components that go into building a circuit, a number of reactions occur, such as reactance and impedance. Just as two primary colors make up a secondary color, so, too, do certain electrical reactions give rise to secondary reactions creating more advanced functions.
Finally, the last step in learning electronics is to take what you already know and apply it. This learning process is likely to extend beyond any learning program you may be undergoing through to your first few years practicing. No course, no matter how comprehensive, is enough to teach you all there is about electronics. The more you practice building circuits, the more you learn until you realize that there will never be a time you have figured it all out.
That said, there is a starting point to everything, and a comprehensive learning program will lay the foundations you need to develop.
In order to begin learning electronics, knowledge of physics and mathematics is a necessary requirement, at least to some degree. Fortunately for most, what you need to learn before getting into the science is covered in high school making it accessible to anyone interested. Other than that, any halfway decent learning program should guide you through from basic concepts to more complicated builds, thus broadening its reach. Given just how beneficial it is to learn electronics, no one should expect it to be too easy, as that would be an injustice to the science. Some effort in figuring it all out is something to be expected. And that’s a good thing.
There are many ways to learn electronics. These range from local programs offered in physical locations near you to online options that can be taken at home. The question really isn’t whether it is possible to learn electronics, rather, whether learning is possible when considering various factors. As previously mentioned, knowing your level of understanding on the subject is important, since will decide what level you should start with. Schedules, locations, and affordability are all things to consider when looking for a course or learning program. While there may be options near you that meet those qualifications, and not to mention the added advantage of having a teacher to guide your hand through everything, that isn’t the case for most people looking to learn electronics. Assuming any such places can be found near you, they are likely to be far more expensive, almost guaranteeing at least one of the aforementioned three requirements is sacrificed. Meeting all three requirements is hard, yet not impossible, as is exemplified by one outstanding learning program.
The Introduction to Basic Electronics course is just that. It manages to somehow cover all the requirements that make it simply the best course for anyone and everyone looking to learn electronics. Here are a few great reasons that show just why this is the best course to opt for:
The Teacher: Greg Carpenter is the brains behind the whole program. After having worked with electrons for nearly half a century, it is safe to say that Greg knows what he’s doing, and he intends to do something about that. The entire program is really just a compilation of teacher passing down the mantle to students ready to develop the science. Greg has learned not just what was taught to him, but also all of what you learn when you spend decades on the job.
Accessibility: All the material in the course can be easily attained with the simple click of a button. After downloading the two books, audio reviews, and chapter review notes, everything you need is made available to you. The price it comes at, considering all the content offered, is also something anyone can afford.
A Step-by-Step Guide: Starting off with the absolute basics, the course covers all the foundations of electronics in a way that is easy to understand. Though the language may be polite, it is in no way lacking, since every single theoretical topic that can be covered is covered. This means addressing the necessary concepts involved in electronics and circuit building, as well as familiarizing a student with some of the more technical terms. Once this is done, the entirety of which is contained in the first book, learners can progress to the second stage of the learning process. The second book then goes on to guide students on ways to apply what they have learned. Even though it claims to be an introductory course, it goes further than this, and necessarily so.
By providing guidance on how to be build circuits, it ensures that students properly understand theoretical concepts, since success is determined by said understanding. It also does this in recognition of the simple fact that actually building a circuit is an encouraging reward. If you spend too much time studying theory without putting any of your knowledge into practice, you might forget what attracted you to learn electronics in the first place. With a few projects included, all of which are basic enough for anyone to execute, they are designed to specifically give students a sense of satisfaction. In short, the course is more of a guide, turning those who know nothing into prepared technicians with all the tools to become masters themselves.
Looking Ahead: As if all of what it already offers isn’t enough, there is more source material Greg has prepared, all of which further broadens a student’s understanding of the field. This includes aides to help remember technical terms, exploration on more theoretical concepts, and guides on how to build like a pro.
The Introduction to Basic Electronics course learning program clearly offers all that is needed to kickstart a career. The fact that it presents itself in a convenient way and to the benefit of many just goes to show why it is the best course out there for those who want to learn electronics.
Confidence is key to moving forward with an electronics career. It is also important for those who want to step up their level and try studying the science at a university level. Whether your intentions are to take a simple introductory course, supplement what you are already learning, or just learn about electronics, the Introduction to Basic Electronics course will do the job for you. It provides all the learning and practice you need to build your confidence and move forward.
What you do with your acquired knowledge is entirely up to you, but given all the possibilities that the skill offers you, it is hard to think that nothing will come of it. In any case, you do have to start from somewhere, and opting the for the right guidance will serve you well in the years and decades to follow.
