Electronic basic components - LED, resistors, transistors and capacitors

First thing to learn about electronics is what parts does what, I read thought several materials like books and webpages but find it a bit difficult to understand it completely. Later I discover that Makezine did a series of very clearly explained video on YouTube on the following components called Makezine presents :-

Resistors

Light Emitting Diode (LED)




Transistor




Capacitor




Inductor



and last one is Integrated Circuits AKA microchips or "chips" in short.




As most of the electronic books explain the above components like a textbook style just to fill up the pages, the above video show it in a more lively way with some historical background about how the components was invented or discovered.
