Why does the rate of change of potential difference between two
Current, I, is related to voltage by Ohm''s law, I=V/R.As the capacitor discharges, the current will decrease as less charge is "released" from the capacitor. From Ohm''s law, we would expect lower currents to result in lower potential differences (assuming a constant resistance), thus as the current decreases, the potential difference also decreases, at an exponential rate.

6 FAQs about [The difference between the two plates of the capacitor]
Why does a capacitor have a higher capacitance than a plate?
Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its plates. In other words, larger plates, smaller distance, more capacitance.
What determines the capacitance of a parallel plate capacitor?
The capacitance of the parallel plate capacitor determines the amount of charge that it can hold. If you see the above equation, you will see that greater the value of C, greater will be the charge that a capacitor can hold. Therefore we can see that the capacitance depends upon: The distance d between two plates.
What is the potential difference between a capacitor and a plate?
A capacitor holds 0.2C 0.2 C of charge when it has a potential difference of 500V 500 V between its plates. If the same capacitor holds 0.15C 0.15 C of charge, what is the potential difference between its plates? In practice, capacitors always have an insulating material between the two plates.
Why is there no electric field between the plates of a capacitor?
In each plate of the capacitor, there are many negative and positive charges, but the number of negative charges balances the number of positive charges, so that there is no net charge, and therefore no electric field between the plates.
Why do capacitors have different physical characteristics?
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage across their plates. The capacitance of a capacitor is defined as the ratio of the maximum charge that can be stored in a capacitor to the applied voltage across its plates.
How do capacitors store electrical charge between plates?
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
