The capacitance won't change, or it won't change significantly. The capacitance is simply the charge/voltage ratio - and if the charge doubles, the voltage will also double.
Capacitance is determined by the physical properties of the capacitor (plate separation, plate area, and dielectric). The unit for capacitance (farad) is a coulomb per volt. So the capacitance is the amount of charge (coulombs) that the plates will hold at a given voltage.

What is D in capacitance measurement?
You think probable to the distance between the plates of the capacitor.
What happens when tech tonic plates collide with oceanic plates?
Tectonic plates are oceanic plates. But when tectonic plates collide and a convergent boundary earthquakes occur.
What happens when two tectonic plates rub back and forth?
an earthquake happens
What happens in the mantle that makes the plates move?
sing
What causes two continental plates to diverge?
An earth quake. This happens because the vibrations force the plates apart
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.
Does charge on a parallel plate capacitor depend on distance between the plates?
Capacitance is the ability of a body to store an electricalcharge. Any object that can be electrically charged exhibits capacitance. A common form of energy storage device is a parallel-platecapacitor. 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, andV gives the voltage between the plates, then the capacitance C is given by
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
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.
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 principle of capacitor?
The simplest capacitor is just two parallel metal plates, not touching. When a battery is connected across the plates, the plates become charged, with electric charges sitting facing each other, positive ones on the positive plate and negative on the negative. When the battery is removed, the charges stay where they are so the capacitor is a way to store electric charge and energy, a bit like a rechargeable battery. Supposing the battery was 1 v and the charge is +1 coulomb on one plate and -1 coulomb on the other. That means the capacitor has a capacitance of 1 Farad. The amount of charge a capacitor can store is given by the formula Q = CxV in other words the charge is the capacitance times the voltage. So a large capacitance can store more charge for the same voltage. With the 2-plate capacitor the capacitance increases if the plates are bigger and also if they are closer together. Larger capacitance can be produced by using two sets of interleaved plates. Each set has all its plates connected together, and there is dielectric insulation between all the plates.
What is an importance of capacitance?
capacitor is a device to store charge .it is based on the concept that when the potential of the capacitor is decreased it can gain some more charge so Q = CV where V is potential and Q is the charge stored then C is the capacitance. capacitance is the ability of the capacitor to store charge. expression for capacitance is C=ɛA/d where ɛis permittivity and A is area of capacitor plates ,d is plate separation.
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 are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
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 are the three factors that determine the charge of a capacitor?
If you mean the capacity of the capacitor then, Factors are:- Area of of overlap of the plates Separation of the plates How good is the insulating material between the plates (the dielectric) If you mean how large a charge can be stored then, Factors are:- The capacitance of the capacitor (C). The applied voltage (V). Charge Q =CxV V cannot exceed the dielectric's breakdown voltage.
What is the meaning of electronic capacitor?
A capacitor could be two parallel plates close together but unconnected, and then the plates are connected to either side of a battery. Current flowing causes charge to build up on the plates, positive on one plate and negative on the other, until the voltage across the capacitor is equal to the battery voltage. The amount of charge that has flowed in, divided by the voltage, is called the capacitance, measured in Farads.If the battery was one volt, and the charge was one coulomb (i.e. one amp for one second), then the capacitor has a capacitance of one Farad.Usually capacitors are measured in microfarads or picofarads.
