What is the difference between charge density and charge carrier density? If each electron has an elementary charge of -1 (natural units), and the electric field and voltage are manifestations of the effects of charge, then why is charge referred to as seemingly separate of electrons in text? (in this post, I will be asking about charge wrt electrons, not protons or other charge carriers)
If an electric field's strength is based on the amount of charge, then wouldn't that necessarily mean the strength is resultant from the specific number of electrons at a specific spot generating the surrounding field? Is there a way to generate a greater electric field strength without more electrons? Is the potential energy of the field generated by the amount of electrons? Is a stronger electric field necessarily caused by more electrons?
As for voltage, would the electrostatic potential simply be the relative difference between the amount of electrons present in separate materials? Is there a maximum difference (voltage) that a material can have ( 0 electrons vs most electrons a material can hold)? Is there a maximum electron density for any physical material? Is the only way to increase the charge of a capacitor is increase the number of electrons or electron density of the plate?
Does the electric field flow around the electrons and is not dependent on their exact position, or just around the wire? http://amasci.com/miscon/eleca.html#current"
I attempted to read a calculus based physics book on electromagnetics, but did not make much headway. The book treats charge as if is some mathematical concept that exists without physical form (the electron or any charged particle). Is this true? Is charge some type of free-floating ether that manifests itself as the electric field and creates electrostatic potential independent of electrons and other charge carriers? Most of my physics knowledge comes from a conceptual physics book and this http://amasci.com/miscon/elect.html" and have taken two semesters of calculus, so I apologize if I have made some serious errors in my understanding or am asking questions that are too advanced for my mathematics or physics level. I have used the site mentioned above extensively, and am also wondering how good of a source it is for learning about electromagnetics.
Thank you
