I am determined to learn electronics from the ground up and to be completely familiar with all the concepts.
It understand all the maths but it still doesn't give me a real "feel" for the concepts.
One writer I came across talked about thinking of the capacitors in a circuit as actually rising and falling (in space!) as a way of intuitively understanding what's occurring.
This is the kind of intuitive feel tha tI want to have.
Does anyone have suggestions as to books/authors/resources that could help here please?
Cheers.
Go back to square one!
Get to know your way around resistive circuits first.
Learn Ohm's Law,---think about it as a real thing,not as just some "Maths".
Try to visualise what is happening.
Learn Kirchoff's Law---try to analyse circuits using it.
Capacitors:-Capacitors almost always need to be explained using models which are not necessarily correct,but do to get the idea over.
This is how I learnt:-
WARNING! WARNING!-refers to Electron Flow--EEs may want to turn away,now.Initially,a capacitor has no charge but it does have a few free electrons on its plates.
When it is connected to a battery,free electrons at the positive connected plate are attracted to the positive batt terminal.
Current flows until that plate is at the same potential as the positive batt terminal.
It now appears positive with respect to the other plate.
This sets up an electric field between the plates.
Free electrons in the negative plate are attracted by the positive plate's potential,but cannot flow through the dielectric,& mass at the plate surface as close as they can get to the source of attraction,robbing the rest of the plate of free electrons.
This looks like a positive charge to the batt negative terminal & current flows until the capacitor negative plate & the batt terminal are at the same potential .
The capacitor is now "charged".
AC current through capacitors is simply a series of charge/discharge cycles.
This description is better with a blackboard & diagrams,plus it is simplified to help people get a working understanding of how the things work.
It doesn't happen in nice steps like in the above but simultaneously.
Also,"free electrons" is a bit of a simplification for "electrons which may be readily dislodged from their associated atoms".
The "Electric Field" in the dielectric is shown in various ways in different diagrams.
You can chase these up later,but right now,this model makes a lot more sense than hydraulics & diaphragms.
