What is the relationship between the the separation distance and the capacitance?

Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. Therefore, as the distance between the plates decreases, capacitance increases.

Does the distance between 2 parallel plate capacitors affect the potential between them?

Because the capacitor is still connected to the power supply the potential difference can’t change. Moving the plates further apart decreases the capacitance, also reducing the charge stored by the capacitor. The potential difference across the capacitor: increases.

What is the relationship between electric field and the distance of separation between the plates of a parallel plate capacitor?

In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.

How is the electric field between the two plates of a parallel plate capacitor?

Easiest explanation: The direction of the electric field is from the positive to the negative plate. In the inner region, between the two capacitor plates, the electric fields due to the two charged plates add up. Hence, the field is uniform throughout.

What is the relationship between the area of the plates of the capacitor to its capacitance?

Larger plates provide greater capacity to store electric charge. Therefore, as the area of the plates increase, capacitance increases. Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together.

What happens to the capacitance of a parallel plate capacitor if the area of its plate is doubled?

If the area is doubled with the other parameters being constant, then the capacitance would double. If the distance of separation were doubled with the others constant, then the capacitance would be halved.

How does the capacitance of a parallel plate capacitor vary with area of plates?

When a capacitor is fully charged there is a potential difference, p.d. between its plates, and the larger the area of the plates and/or the smaller the distance between them (known as separation) the greater will be the charge that the capacitor can hold and the greater will be its Capacitance.
