What resource (web pages, book, youtube) can I use to help me with reading schematics? On a chapter by chapter basis (diode, capacitor) I get it. But when faced with reading some of these schematics with many componenents for projects I just have difficulty determining the direction of current flow and keeping track of it. I'm surprised I find it so hard because I'm a programmer, but these larger schematics are kicking my rear. Any advise appreciated.

 

Hello,

For all the electronic symols you can have a look in the reference book of our eBooks:
http://www.allaboutcircuits.com/vol_5/index.html
Chapter 9 is for the symbols:

If you are looking for the relation of voltages and currents in a network take a look at the chapter on network analysis:

Thank you Bertus. The Network Analysis chapter looks like what I need to read. The more I refer to the allaboutcircuirts web site book/documentation the more I get irritated about having to pay for this $100 text book when a better source is online free. Thanks again.

 

Hello,

There are also a lot of lectures on the web that you can watch for free:

This is only one page from the engineering list of lectures:

OMG Bertus. This is like who needs a physical classroom. Thanks much!

 

Thanks from me too, Bertus!!! I'm working on protective relay theory, but without the professor, bumbling around solo is not getting me anywhere.
