I'm not really sure what type of corrections are of interest, but this was just a minor grammatical error that I found while reading today. This is taken from the paragraph directly above the diagrams for real battery and ideal battery.
"Although we generally consider a cell or battery in a circuit to be a perfect source of voltage (absolutely constant), the current through it dictated solely by the external resistance of the circuit to which it is attached, this is not entirely true in real life. Since every cell or battery contains some internal resistance, that resistance must affect the current in any given circuit:"
I believe the word "is" was left out. The current through it is dictated solely by the external resistance...
