If you've ever looked down on a city from a skyscraper window, you'll have marveled at all the tiny little buildings beneath you and the streets linking them together in all sorts of intricate ways. Every building has a function and the streets, which allow people to travel from one part of a city to another or visit different buildings in turn, make all the buildings work together. The collection of buildings, the way they're arranged, and the many connections between them is what makes a vibrant city so much more than the sum of its individual parts.
The circuits inside pieces of electronic equipment are a bit like cities too: they're packed with components (similar to buildings) that do different jobs and the components are linked together by cables or printed metal connections (similar to streets). Unlike in a city, where virtually every building is unique and even two supposedly identical homes or office blocks may be subtly different, electronic circuits are built up from a small number of standard components. But, just like LEGO®, you can put these components together in an infinite number of different places so they do an infinite number of different jobs. Continue reading from Explain that Stuff
If you are new to electronics or starting to build electronic circuits, then the important thing to do is to get familiar with few Basic Electronic Components and Equipment. Without understanding these basic electronic components i.e. their values, ratings, purpose etc. your circuit design might not function as expected.
There are many electronic components like Resistors, Capacitors, LEDs, Transistors, etc. and there are also many equipment like a Power Supply, Oscilloscope, Function Generator (or Signal Generator), Multimeter, etc.
In this tutorial, you can get a brief overview of few of the most common basic electronic components. For more information about a particular component, you can check out the link associated with individual component. Continue reading from Electronics Hub
