The value of C depends upon the following: The size and shape of the conductor, The nature of the medium surrounding the conductor; The position of the neighbouring charges. It does not, however, depend upon the material of the conductor. Further, let V = 1, Therefore from Eqn. (1), Q = C or C = Q.
The amount of charge that a capacitor can store is determined by its capacitance, which is measured in farads (F). The capacitance of a capacitor depends on the surface area of its plates, the distance between them, and the dielectric constant of the material between them. Capacitors are used in a variety of electrical and electronic circuits.
The quantity of charge held in a capacitor depends on both capacitance, as defined above, and the voltage across the capacitor. The same charge can be stored in a large capacitor at low voltage and a small capacitor at high voltage. Example 1 (A) A 10 µF capacitor is charged to a potential difference of 100 V. Calculate the charge.
The flow of electrons onto the plates is known as the capacitors Charging Current which continues to flow until the voltage across both plates (and hence the capacitor) is equal to the applied voltage Vc. At this point the capacitor is said to be “fully charged” with electrons.
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
The current flowing through the capacitor is directly proportional to the capacitance of a capacitor and the rate of voltage. Larger the current, higher is the capacitance of the circuit and higher the applied voltage,larger the current flowing through the circuit. If voltage is constant then charge is also constant.Thus there is no flow of charge.

$begingroup$ What you are learning about is an ideal capacitor, made from a material with zero electrical resistance. Of course such a thing doesn''t exist, but if the resistance is small, it is a pretty good approximation.

First, the amount of charge that a capacitor can charge up to at a certain given voltage depends on the capacitor itself. How much charge a capacitor can retain and at what voltage is determined by the specifications of the capacitor. Different capacitors have different charge capacities.
There are three basic factors of capacitor construction determining the amount of capacitance created.
