When you drain a cap you increase the current and as they drain the voltage drops. Right now you are thinking something along the lines of "if I push something harder it MUST speed up, while forgetting the fact that if what you are pushing has weight added to it, it doesn't speed up and can even slow down. Understand that those graphs an things you are looking at are simplifications with assumptions about the conditions, but there is a control system underneath. | |
