[Reduce DC voltage, How? please..]

Alun:  I kind of understand how you got your equation. 
I don't really get the concept behind it setting the Iadj*R2 = 0.  Could you explain this in more detail?

[p type and n type]

Malvino's Electronic Principles does a good job of explaining the concept.

[How did I blow out a leg of a Bridge Rectifier(BR82D)]

thanks for the help Ldanielrosa.  I found out what was happening.  My function generator could only supply enough current to turn on 2 of the diodes resulting in the other two not rectifying.  I tested it on a transformer and it worked just fine.  Just something I never thought about.  :P

[How did I blow out a leg of a Bridge Rectifier(BR82D)]

So I'm building your basic DC power supply using Bridge Rectifier(BR82D) 200v 2A.  When I go to test the thing with my function generator, 18v P-P at 60Hz and look at it with my scope I get half wave rectification. 

PROCEDURE - After I first assembled the thing, I checked the output voltage of the regulator with my scope which looked to be OK.  Then proceded to look at the rectification with my scope on the legs of the BR82D, to find that it's only rectifying a half wave.  I can only conclude that I blew a leg out on the thing somehow when connecting the clips.  But I haven't any clue how I could have done so.  Im guessing that it may have to do with grounding, but I am not positive.  Anyone have any ideas?  Comments?  Maybe it had to do with which clips (+ or -) I connected first from the scope.

Hopefully this is a good home for this.

[Anyone Know of any good Math Books?]

thank you, I'll look into those :)

[Anyone Know of any good Math Books?]

Sorry, it's really a vague question.

[Barrier potential discrepancy]

.7v for silicon and .3v for germanium and you subtract this from the source.

If you want to be more exact in your answers, you can compensate for bulk resistance(which is the resistances of the p and n regions together) which is usually around .23ohms for si, but is usally negligible unless your striving for accuracy or depending on what your trying to accomplish.

[What do the Address and Data Pins do on an EPROM?]

It sure did!  It's more than I could have asked for.  Thanks :D

[What do the Address and Data Pins do on an EPROM?]

Im trying to learn a little bit about how EPROMs work and I don't quite understand how the Address and data pins work.  The address pins(address bus) recieves the address that the computer or whatever is reading it supplies, and the data(data bus) pins outputs the value that is stored in the byte through the 8 pins(8 bits) right?  Can some make this a little clearer for me?  Also, if anyone has any good web-pages regarding this material I'd really like to take a look at it.  Thanks!

[Free sample chips!]

Does anyone know if you can get

Atmel 29C256's

Im not really sure how to go about doing this.

[Hey guys Im new here. Just wanted to say hi!]

Hi, I found this website off of another forum.  Im going into EE.  I probably don't know as much as you guys do, so Ill probably do more learning more than helping! So thanks in advance :)
