Electronic Parts.......?

Question

what's a hole/electron?? Also, I know there's a +/- side to diodes, so which way does it go for oneway?

Answer 1

Capacitor can  absorb and discharge electrical energy;Transistor is a Valve that controls Electron and Hole flow;Diode is a One Way valve and an Integrated Circuit may contain All of the above  Electrons are Negative and flow from higher density {voltage}to lower density[positive] this is in reverse to the arrows in schematic drawings Electrons flow in the opposite direction from the arrows written on diodes and Transistors the arrows point to Hole flow

Answer 2

It is possible to write several books by answering your questions. if you really wants to teach electronics yourself i recommend you to get some books.

A good one which does not require too much math (only high school math) to be understood is: PRACTICAL ELECTRONICS FOR INVENTORS, Paul Scherz. You can

get it from Amazon.

If you want to do it the free way you can visit some good electronics sites, for instead:
