How is the current that pushes electricity through the space between the two plates of the capacitor called?
But why and how does AC pass through the capacitor?
It does not. An alternating current will charge and discharge one plate, which means that the electrical field will change which again will change the charge on the other plate. A change in the charge means that a current will pass out of or come onto the plate. Thus, it seems as if current "passes through", but in reality it is interaction between current, charge and field.But why and how does AC pass through the capacitor?
