Im trying to find a book that would explain what is actually happening in laymans terms / qualitatively and THEN go into the equations matching things up.

For example:

With a circuit that has an AC source and a resister and capacitor. The big picture (I was told I am right) is that as the source increases the capacitor charges up, when the source starts going down, because of the voltage drop across the resistor meaning the capacitor isn't charged to the peak of the source means even though the source is going down its still charging the capacitor, then once the source is less that the capacitor the capacitor starts to discharge.

So the "total" or "resultant" voltage in the circuit is a combination of the capacitor and source voltage acting together.

Kind of like a net force, if you push a ball left with 10N and right with 8N it will go left with the force of 2N.

When I asked if I was right my lecturer said "Putting it that way you are right, from a physics point of view, I see where you are coming from".

And its these kind of explanations that, for me anyway, seem to be lacking in the books. Its ok when you know what's going on and just need the equations but if you don't know what exactly is happening your just going on blind faith.

Another kind of example is in the beginning on "An Elementary Treatise on Electricity", Its written in a way that a layman kind relate to and understand but then it goes into the equations...
