Identifying Capacitors and other things

Postby gruforevs » 23 May 2010, 02:49

I have been tearing apart old broken electronics lately and am wondering how to identify the correct name of capacitors and resistors etc. I google everything that are written on them and nothing really comes up. Is there some convention to naming capacitors and other stuff from the brand/random numbers and letters written on them?

once again I wholeheartedly apologize for my newbiness and thank you for the help.

One more question, how do you tell the difference between types of caps? Like, what do ceramic caps look like in comparison to silver micas or film or orange drops and what real difference do they make?

Thanks again for your help :D
