You can compute it from the area of the plates, the distance between them, and the dielectric constant of whatever is between them. I'll leave it up to you to lookup the equation (or derive it if you want to get ambitious, it really isn't too hard) and find a published table of dielectric constants.

Can you double the volts by connecting two capacitors?
Two capacitors can be connected in series to double the voltage rating, but they must be identical capacitors and they should each have a resistor in parallel to equalise the voltages, the resistors chosen to pass about 1 mA. With two capacitors in series the overall capacitance is half the capacitance of either capacitor. The combination stores equal charge at double the voltage and the stored energy is doubled.
What is divergent plates?
separating plates
What is collide divide slide?

What are the two plates inside the earth called?
If you are thinking of tectonic plates then there are more than two.
Which two plates meet at haiti?
North America and Caribbean plates.
Are all electrolytic capacitors the same?
Type your answer here... As per the definition of capacitor it is a device which made up of dielectric material in between two parallel metal plates. Even two metal plates placed parallel in open area will result in capacitance since air is also dielectric in nature..
Why capacitance decrease with an increase in distance between plates?
This is because a capacitor works on the principal of electro-statics. The closer the plates are to each other, the greater the effect of the positive and negative ions attraction across the dielectric constant. The further the plates are from each other, the lesser the attraction hence lower capacitance. Larger plate area increases capacitance also. If you have ever taken apart an electrolytic capacitor, what you'll find is two thin strips of aluminum foil with a strip of paper between them that was soaked in the electrolytic acid. When you unroll the assembly (wearing gloves), you'll find that the plates are quite long. This makes up the surface area of the two plates, which is one of the factors that determines the capacitance.
When you put two 10 µF capacitors in parallel the equivalent capacitance would be?
With capacitors in parallel you can just add the microfarads.
If two identical capacitors connected parallel then effective capacitance?

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.
What is the effect of dielectric on the capacitance of a capacitor?
Any variation of the charge within a p-n diode with an applied voltage variation yields a capacitance wich must be added to the circuit model of a p-n diode. The capacitance associated with the charge variation in the depletion layer is called the junction capacitance, while the capacitance associated with the excess carriers in the quasi-neutral region is called the diffusion capacitance. Both types of capacitances are non-linear so that we will derive the small-signal capacitance in each case. We will find that the junction capacitance dominates for reverse-biased diodes, while the diffusion capacitance dominates in strongly forward-biased diodes. The total capacitance is the sum of both.
What is the equivalence capacitance of combinations?
Equivalence capacitance for system of two capacitors in parallel circuit is Ce = C1 + C2 Equivalence capacitance for system of two capacitors in serial circuit is 1/Ce = 1/C1 + 1/C2
Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
Why can't two capacitor plates be far away from each other if it's really just the battery creating the potential difference between the plates?
Capacitance is directly proportional to the area of the plates divided by the distance between the two plates. The farther away the plates are the lower capacitance will be. A capacitor stores energy in the electric field between the two plates. If those plates are very far apart, the field gets crappy real fast.
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.
What should we do to increase the capacitance of a capacitor?
Not much if it is a fixed capaitor. If it is a variable capacitor, rotating the shaft to mesh the two sets of plates more closely will increase the capacitance.
Two capacitors of 2µF are connected in parallel A 1 µF capacitor is added in series What is the combined capacitance?
For capacitors connected in parallel the total capacitance is the sum of all the individual capacitances. The total capacitance of the circuit may by calculated using the formula: where all capacitances are in the same units.
