The potential grows linearly as we move away from the positive plate towards the negative plate i.e. the potential difference between the point and the negative plate is propotional to the distance from the negative plate. Because the potential of the negative plate is set to zero, then this change is just equal to the potential itself

6 FAQs about [Judgment of positive and negative points on capacitor plates]
Is capacitor potential positive or negative?
The capacitor potential is always positive except in cases where the defined positive plate happens to have a negative charge and therefore a negative potential (e.g., see § 5.5). In words, capacitance is how much charge a capacitor can hold per capacitor voltage (i.e., how many coulombs per volt).
Is a capacitor a positive or negative plate?
The capacitor charge is defined to Q which formally is always positive. The capacitor charge can be negative in cases where one plate is defined as the positive plate for some derivational or practical reason and this plate happens to acquire a negative charge (e.g., see § 5.5). In electrostatic equilibrium, the plates are EQUIPOTENTIALS.
What is the difference between plate potential and capacitor potential?
The potential difference V between the PLATES is the capacitor potential: it is the positive plate potential minus the negative plate potential. The capacitor potential is always positive except in cases where the defined positive plate happens to have a negative charge and therefore a negative potential (e.g., see § 5.5).
How do you determine if a capacitor is positive or negative?
Say we had a collection of isolated capacitors with capacitances Ci, charges Qi, and potentials Vi: note Qi = CiVi of course. We then order them with the fiducial positive plates all on the left say. If a plate happens to be actually negative, then its Qi and Vi are negative.
What happens if a capacitor has a large potential difference?
If the potential difference gets too large (which implies a large electric field), charge will start to flow between the plates. It can be pulled off the surface of the plates if the capacitor has vacuum between the plates and if there is a dielectric between the plates (which is usual), then the dielectric can break down (i.e., start to conduct).
What is the polarity of a capacitor?
The positive charge on one plate is exactly equal to the negative charge on the other. The polarity of a capacitor refers to the direction of the electric field within the component. This polarity is crucial for the correct operation of the capacitor. Not all capacitors have polarity; it’s primarily associated with electrolytic capacitors.
