What are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
What is the Relationship between length of cable and capacitance?
The capacitance of a cable is directly related to its length; as the length of the cable increases, the capacitance also increases. This is because capacitance is determined by the surface area of the conductors and the distance between them, with longer cables providing more surface area for charge storage. Additionally, other factors such as the dielectric material between the conductors and their geometry also influence capacitance. Overall, longer cables typically exhibit higher capacitance values, impacting signal integrity in electrical systems.
Definition of a capacitance in mosfet?
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.
What is the difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
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.
Why does capacitance increase when the distance between the plates of a capacitor is increased?
you have it reversed. capacitance increases with decrease in distance of plates.
What are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
What happens to the capacitance fi the charge on the plates of a capacitor is doubled?
The capacitance doesn't depend on the charge stored in it. The capacitor has the same capacitance whether it's charged by a DC and just holding it, or in an AC circuit where the charge on it keeps changing and reversing, or in a box on the shelf connected to nothing and not charged at all.
What is D in capacitance measurement?
You think probable to the distance between the plates of the capacitor.
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.
Why capacitance increase with a decrease in distance between plates?
Capacitance increases with a decrease in distance between plates because the electric field between the plates becomes stronger, storing more electric charge per unit voltage. This results in a higher capacitance value since the plates can hold more charge for the same applied voltage.
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.
Is it true if supply voltage is increased the capacitance of a RC circuit will decrease?
No. Capacitance is determined by the area of overlap of its plates, the distance between them, and the absolute permittivity of its dielectric.
What is the effect of changing the distance between the plates of a capacitor on the charge stored on the plates?
Changing the distance between the plates of a capacitor affects the charge stored on the plates. As the distance decreases, the capacitance increases, leading to a higher charge stored on the plates. Conversely, increasing the distance between the plates decreases the capacitance and results in a lower charge stored on the plates.

How maximum and minimum capacitance can be obtained?
Maximum capacitance can be achieved by increasing the surface area of the conductive plates, reducing the distance between them, and using a dielectric material with a high permittivity. Conversely, minimum capacitance can be obtained by decreasing the surface area of the plates, increasing the distance between them, or using a dielectric with a low permittivity. Additionally, removing the dielectric material altogether can also yield minimal capacitance. Thus, the design and material selection play crucial roles in determining capacitance values.
What is the Relationship between length of cable and capacitance?
The capacitance of a cable is directly related to its length; as the length of the cable increases, the capacitance also increases. This is because capacitance is determined by the surface area of the conductors and the distance between them, with longer cables providing more surface area for charge storage. Additionally, other factors such as the dielectric material between the conductors and their geometry also influence capacitance.
