I am taking the Coursera course on DC linear circuits and have various questions in parallel. I found the 80% related question "How does current flow through a voltage source" and my question differs in that it is related to a capacitor-battery circuit as described by the Organic Chemistry Tutor here. According to Organic Chemistry Tutor, in a circuit with a "+" battery pole connected to one capacitor's plate and a "-" pole - to another, the battery pulls electrons from one capacitor's plate and makes them flow through the "+" pole, the battery itself and it's "-" pole to another plate thus charging the capacitor. The question is why aren't electrons from the plate attracted to the "+" pole of the battery by sticking to the cathode (reduce it by giving up the electrons) ? A parallel question is why the electrons from the plate aren't repelled back by the "-" pole of the battery and rather flow through it?
As is mentioned in the related question, the electrolite in the battery actually conducts the electrons pulled from the capacitor's plate. A subquestion may be: should the current in such circuit consist from both electrons pulled from the capacitor's plate and the electrons supplied by the battery?
