The current flowing through a capacitor equals C*dV/dt, I'm aware of that. What I don't understand is the physics of the process. Why does a capacitor pass pulsed DC (0-10V for example) when charge carriers don't change their direction?
Even if I use the "water analogy" it doesn't make sense. The flow moves in one direction, so the "diaphragm" will not be able to move back and forth.
