What is the effect on pressure of doubling the surface area on which a force is being exerted?
pressure will be halved
If the acceleration of a charged particle between plates in a plate capacitor is a at halfway between the plates why will the particle experience the same acceleration when its 1 quarter of the way?
Because the field between plates in a capacitor is homogenous. It has the same strength in every point of the field.
Does capacitance exist between two thin current-carrying conductors Explain?
The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like the dielectric medium between them.A capacitor is a device used to store electrical charge and electrical energy.
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 two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
How to find the area of the capacitor plate, knowing the diametr?

How a capacitor store charge?
by using capacitor plates. The length,area ,thickness and type of the plate determines the amount of charge a capacitor can store.
If you have a parallel plate capacitor of plate area 'A' and plate separation t and having a capacity C and a metallic plate r of area A and of negligible thickness is introduced in the capacitor at a?
Pursuant to Ohms Law, we can deduce that the answer is the square root of Pi divided by C*R+A.
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.
What will happen to the capacity of a parallel plate capacitor in which a conductor plate is introduced?
it decreases...............
How can you identify that which plate of capacitor is positively charged?
FOR tESTING THE SIGN OF CHARGE ON BODY, a device called GOLD LEAF ELECTROSCOPE. When the disc of a positively charged is touched with any plate of the charge capacitor. IF the divergence of gold leaf increases, then the plate is positively charged and if the divergence in the leaf decrease then the plate of the capacitor is nagatively charged.
Which plate of capacitor is plus charged?
Whichever plate is connected to the positive end of a battery.
What is the capacitance of a parallel plate capacitor with a dielectric of oil-soaked paper The dielectric constant is 3.8 the distance between the plates is 0.00625 inches and the plate area is 0.25?
3.42*10^-11 farad.
How the pointing vector points be for a parallel plate capacitor which is being charged out?
For a parallel plate capacitor is The poynting vector points everywhere radially outward of the volume between plates.
What is stored charge?
In a capacitor it is a build up of electrons on a plate.
An air-filled parallel-plate capacitor is connected to a battery and allowed to charge up Now a slab of dielectric material is placed between the plates of the capacitor while the capacitor is still?
the charge on the capacitor had increased.
A parallel plate capacitor has a plate separation of 1.0 mm How much potential difference can be placed across the capacitor before dielectric breakdown of air occurs?
You need more information than this to find your solution. There will be a a value for the electric field at which point the air will break down. you also need the area of one of the capacitors and the capacitence
