Basic electronics. LAST MODIFIED: Wednesday, 18-Mar-2015 17:25:56 PDT Authored by Ian C. Purdie VK2TIP Find us on Google+ •NEW! The navigation bar to the right is a very comprehensive list of topics in basic electronics and is listed in a suggested order. Following a lot of requests from newcomers I have provided a separate page called "starting out in basic electronics". If you want a reasonably good grounding don't forget to review electron theory and atoms this is the very basis of electronics.
This chapter basic electronics is the most important of all for newcomers. Here you should gain a full understanding of basics electronics. You must have a good grasp of ohms law, an understanding of power, voltage, current and resistance. Capacitance, inductance as well as reactance which leads on to impedance and "Q". Very popular basic electronics topics are impedance matching and the wide variety of transformers ranging from power transformers, audio transformers and wide band rf transformers. NEW! Basic Electronics: Using IC Regulator. Lecture - 1 Introduction to Basic Electronics. Basic Electronics. The goal of this chapter is to provide some basic information about electronic circuits.
We make the assumption that you have no prior knowledge of electronics, electricity, or circuits, and start from the basics. This is an unconventional approach, so it may be interesting, or at least amusing, even if you do have some experience. So, the first question is ``What is an electronic circuit? '' A circuit is a structure that directs and controls electric currents, presumably to perform some useful function. The very name "circuit" implies that the structure is closed, something like a loop. That is all very well, but this answer immediately raises a new question: "What is an electric current? " No one knows what charge is anymore than anyone knows what gravity is. We just invent the name to represent the source of the physical force that can be observed. We call the two styles positive charge, , and (you guessed it) negative charge, .
You cannot create it and you cannot annihilate it. Basic Electronics.
