What is the amount of charge a capacitor can store per volt of potential difference?

permittivity
dielectric constant
capacitance
electric potential energy

The capacitance is defined as the relationship between the electric charge of each conductor and the potential difference between them. That is, it is the capacity of a device to store electrical charge.

In other words:

It is the property that bodies have to maintain an electric charge.

Mathematically it is defined as:

where:

is the capacitance value of a capacitor. Its unit is Farad ; named in honor of the physicist Michael Faraday

is the electric charge of the conductor, measured in coulombs .

is the electric potential to which the conductor is located, measured in Volt.

It should be noted that capacitance is always a positive value.
