This chapter basic electronics is the most important of all for newcomers. Without a thorough grasp of basic electronics you will never fully understand the later and much more complicated electronics tutorials. As a suggestion start by reviewing "starting out in basic electronics" followed by some radio electronics terminology. We then cover electron theory and atoms, attenuators, capacitance, current, digital basics, impedance, inductance, integrated circuits, ohms law, power supply, Q, reactance, resistance, resonance, transformers, transistors and voltage.

BASIC ELECTRONICS

The navigation bar to the right is a very comprehensive list of topics in basic electronics and is listed in a suggested order.

THIS BASIC ELECTRONICS TUTORIALS SITE

Following a lot of requests from newcomers I have provided a separate page called "starting out in basic electronics". This is a good "check-list" page to start out.

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. Without a thorough grasp of basic electronics you will never fully understand the later and much more complicated electronics tutorials. As a suggestion start by reviewing some radio terminolgy A to L and radio terminolgy M to Z, then come back. In particular I would commend everyone to read my page on earth dangers. I think it ought to be compulsory reading.

Here you should gain a full understanding of basics electronics. The basic electronics topics cover everything necessary for your continued understanding of the much more advanced topics presented later.

OHMS LAW, POWER, VOLTAGE, CURRENT AND RESISTANCE

You must have a good grasp of ohms law, an understanding of power, voltage, current and resistance. These are the first fundamental units we work with in electronics.

CAPACITANCE, INDUCTANCE, REACTANCE, IMPEDANCE AND "Q"

Capacitance, inductance as well as reactance which leads on to impedance and "Q". These are the next essential units to gain an understanding of basic electronics. Once mastered - ohms law, power, voltage, current, resistance, capacitance, inductance, impedance and "Q" you have then covered the very essentials of basic electronics.

MORE BASIC ELECTRONICS - IMPEDANCE MATCHING, TRANSFORMERS

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. We also have a brief introduction to the topic of baluns.

TRANSISTORS, DIODES, INTEGRATED CIRCUITS AND VACUUM TUBES

Obviously in this modern age transistors are the most used active device. This includes the concept that for all practical purposes integrated circuits comprise masses of transistors so arranged as to operate in a specific way. Every basic electronics tutorial should give a reasonable depth of study to these remarkable devices.

The basic electronics tutorials will then proceed to deal with diodes in their many forms, integrated circuits both linear and digital. We have included basic electronics tutorials on vacuum tubes or valves because many people believe they offer advantages transistors do not. There has also been renewed interest in vacuum tube technology in recent years if for no other reason than nostalgia.

POWER SUPPLY

We have included the section on power supplies here because it is also fundamental to basic electronics and every project needs a power supply. That tutorial leads you on to a wide range of other regulated power supply topics.

NEW! A topic I am frequently asked about - switched mode power supplies. Comprehensive resources provided.
