Hi Everyone,
can you please refer me to a site that gives the practical details of all (or most of) the electronic components we generally use to build small to medium sized circuits. For eg. I want a site that gives me information somewhat in this manner...

1. Capacitors: How to identify them (variants etc).
What happenes when you connect it across a supply (also, how to connect it).
How to calculate the time it would take to discharge (or any such useful formulae/notes)
Availability (common values used in common situations).
2. Resistors: Identification (color codes.
...
...

I know it is not possible to list out each and every varient/type or component for that matter, but something that covers as much.

Regards,
Harsha
