Introduction of some Electronics Parts.




An electronic circuit board

An electronic circuit board can contains millions of transistors and many other tiny electronic parts. But what are these parts and what do they do? Take a close look at what goes inside electronics and learn the function of each component.

Few words about Datasheet.


Datasheets are indispensable, but they have limitations. Some are detailed; others are skimpy. Some show you sample schematics as a guide to using a component; many dont. None of them tells you much about how a component works, because thats not their purpose. Often they don’t mention other components that must be added. Some datasheets for DC-DC converters, for instance, say nothing at all about bypass capacitors,

What are Active and Passive components?


An electronic circuit is composed of various types of components. Some of these components are termed as active components because they take part in the transformation of the energy while other components,
which only dissipate or store energy, are called as passive elements. The vacuum tubes, rectifier, transistors are some of-the common active while the resistances, which dissipate the power and energy storing elements such as capacitances and inductances are known as passive elements. The transformers may be regarded as a matching device. The success of any electronic circuit

Electronics - Learning by Discovery

Most introductory guides begin with definitions and facts, and gradually get to the point where you can follow instructions to build a simple circuit.
This blog works the other way around. I want you to start putting components together right away. After you see what happens, you’ll figure out what’s going on. I believe this process of learning by discovery creates a more powerful and lasting experience.

Learning by discovery occurs in serious research, when scientists notice an unusual phenomenon that cannot be explained by current theory, and they start to investigate
