There is a circuit with a battery. Opposite the battery, we have a capacitor. I close the circuit. The current starts at the battery. Current is simply electrons passing through the wire, so the first electron in the line starts to move around until it reaches the 1st plate of the capacitor. What happens when that first electron hits the capacitor? I would say that the plate becomes negatively charged.
Then many electrons hit the plate and it begins to build up more and more negative charge. Now I have 2 questions - when does it stop building charge? And what is happening to the other side (the other plate of the capacitor)?
After whatever happens to the other plate, something must happen to the wire leading back to the negative side of the battery. Do electrons continue to travel along this wire?
