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.
How many square inches are in 10 inch diametr circle?
Area = pi*52 = 78.53981634 square inches
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.
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
Can manufactured 1 fared capacitor?
no, because area of 1 fared capacitor is equal to double area of earth.
A capacitor is a device which stores energy by?
Magic. Look up capacitors on wikipedia!!A capacitor stores electrical charges in its plates.Both wrong. A capacitor stores energy as an electric field developed in the dielectric between its plates. A good dielectric with high permittivity (once called dielectric constant) concentrates this field, allowing more energy to be stored in a capacitor having the same plate area and separation but a dielectric of lower permittivity.
Why capacitance increses in parallel?
To avoid that the plates touch each other. The better the dielectric, the closer the plates can be, thus making the electrostatic field on the opposite plates more intense, which allows for more electrons displaced via the charging circuit to the positive plate and more incomplete atoms (positive charges) left on the negative plate. Remember: Being the dielectric an isolator, there is NEVER current through the capacitor.
How can a capacitor filter the AC and DC?
A capacitor consists of two plates separated from one another by an insulator. These plates are normally thin foil and can be sandwiched around a very thin insulator and wrapped into a small package. Since there is an insulator between the plates, DC connected to the two plates cannot flow as long as you do not exceed the breakdown voltage of the insulator. AC current is a different story. Because the insulator is very thin and the effective plate area is relatively large, a negative charge building up on one plate causes electrons to be repelled from the opposite plate, and as the charge on the first plate reverses and becomes positive, the electrons in the opposite plate are attracted back again. This results in a matching alternating current flow on the opposite side of the capacitor.
On what factors capacitance of a capacitor depends on?
The job of a capacitor is to store charge onto its plates. The amount of electrical charge that a capacitor can store on its plates is known as its Capacitance value and depends upon three main factors.The surface area, A of the two conductive plates which make up the capacitor, the larger the area the greater the capacitance.The distance, d between the two plates, the smaller the distance the greater the capacitance.The type of material which separates the two plates called the "dielectric", the higher the permittivity of the dielectric the greater the capacitance.
How does the size of an electrolyte capacitor vary with its capacitance value?
A: Capacitance vary directly with the area applied the bigger the area the bigger the capacitor. There is another element that will increase the size that is the rating of the capacitor voltage since more material will have to be used to insulate the plates
