zhermes said:Yes, you do seem to be fairly lost on this one.
Is that the only question you had?

One small question remains- I don't understand why is it so intuitive that the capacitor will resist this change?
A parallel-plate capacitor with flipping charge is a type of capacitor that consists of two parallel plates separated by a dielectric material. It is called "flipping" because the charge on each plate can be flipped or reversed by changing the polarity of the voltage source.
When a voltage is applied to the capacitor, electrons from the negative plate are attracted to the positive plate, creating a potential difference between the plates. This creates an electric field between the plates, which stores energy in the form of electric potential energy. The flipping charge occurs when the polarity of the voltage source is changed, causing the electrons to switch plates, thus reversing the charge on each plate.
The capacitance of a parallel-plate capacitor with flipping charge can be calculated using the equation C = ε0A/d, where ε0 is the permittivity of free space, A is the area of the plates, and d is the distance between the plates.
Parallel-plate capacitors with flipping charge are commonly used in electronic circuits for energy storage, filtering, and signal processing. They are also used in various technologies such as touch screens, flash memory, and sensors.
The capacitance and flipping charge of a parallel-plate capacitor can be affected by factors such as the distance between the plates, the area of the plates, and the dielectric material used. Additionally, the voltage and frequency of the applied signal can also impact the capacitance and flipping charge of the capacitor.
