We know the Electric Field, E, is equal to:

E=V/l, where V is voltage, l is distance.

V=E*l

Capacitance, C=q/V, and C=q/(E*l)

Hence capacitance is inversely proportional to the distance separating the plates.

Does increasing the plate area of a capacitor increases the capacitance?

Yes. Increasing the plate area of a capacitor increases the capacitance. The equation of a simple plate capacitor is ...C = ere0(A/D)... where C is capacitance, er is dielectric constant (about 1, for a vacuum), e0 is electric constant (about 8.854 x 10-12 F m-1), A is area of overlap, and D is distance between the plates. (This is only a good estimate if D is small in comparison to A.) Looking at this, you can see that capacitance is proportional to plate area.


How does the capacitance of parallel plate capacitor vary with separation between plates of it?

capacitance is inversely proportional to the separation between the platesproof :-electric field is ;- k/E0where k- surface charge density of the plateand potential difference is given by kl/E0and, capacitance by C=Q/Vso, capacitance is inversely proportional to separation between the plates


How do you increase the value of a capacitor?

A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other

What is the relationship between the electric field and the capacitance of a parallel plate capacitor?

The electric field strength in a parallel plate capacitor is directly proportional to the capacitance of the capacitor. This means that as the capacitance increases, the electric field strength also increases.


How does the basic geometry of a parallel plate capacitor not affect its capacitance?

The basic geometry of a parallel plate capacitor does not affect its capacitance because capacitance is determined by the area of the plates and the distance between them, not their shape or size.


What is the role of a dielectric in enhancing the capacitance of a parallel plate capacitor?

A dielectric in a parallel plate capacitor helps increase the capacitance by reducing the electric field strength between the plates, allowing more charge to be stored.

What would happen to the capacitance of a parallel plate capacitor if one of the plates area is increased?

If the area of one plate of a parallel plate capacitor is increased while keeping the separation between the plates constant, the capacitance of the capacitor will increase. Capacitance is directly proportional to the area of the plates, as described by the formula ( C = \frac{\varepsilon A}{d} ), where ( C ) is capacitance, ( \varepsilon ) is the permittivity of the dielectric material between the plates, ( A ) is the area of the plates, and ( d ) is the separation distance. Thus, a larger plate area allows for greater charge storage, resulting in higher capacitance.


Does charge on a parallel plate capacitor depend on distance between the plates?

No, the charge on a parallel plate capacitor does not depend on the distance between the plates. The charge stored in the capacitor is determined by the voltage applied across the plates and the capacitance of the capacitor. The distance between the plates affects the capacitance of the capacitor, but not the charge stored on it.

What are the methods to find capacitance of a capacitor?

You could measure it with a Capacitance meter. Or you could use the formula:In a parallel plate capacitor, capacitance is directly proportional to the surface area of the conductor plates and inversely proportional to the separation distance between the plates. If the charges on the plates are +q and −q, and V gives the voltage between the plates, then the capacitance C is given byFor further info on the total value of capacitance in series or parallel, Google it.


What is function of second plate in a parallel plate capacitor?

In a parallel plate capacitor, the second plate serves to create an electric field between the two plates when a voltage is applied. This configuration allows the capacitor to store electrical energy in the electric field created between the plates. The separation and area of the plates, along with the dielectric material (if present), determine the capacitor's capacitance, which indicates its ability to store charge. Essentially, the second plate works in conjunction with the first plate to facilitate charge separation and energy storage.
