The capacitance of a capacitor is one farad when one coulomb of charge changes the potential between the plates by one volt. Equally, one farad can be described as the capacitance which stores a one-coulomb charge across a potential difference of one volt. The relationship between capacitance, charge, and potential.

The farad is an extremely large unit of capacitance. In most electronic and electrical equipment, capacitors with values this large are rare -- but not impossible. Most capacitors are generally rated in microfarads, nanofarads or picofarads (pF). The older term for picofarad was micromicrofarad (μμF).
So if this 100uF microfarad capacitor was charged to 12V, we convert the microfarads to farads and then drop these numbers in to see it is storing 0.0072 Joules of energy. We know that the capacitor will charge up to the voltage of the battery. So, if we connected a capacitor like this, what will the voltage across the capacitor be?
So, for this 12V 100uF microfarad capacitor, we convert the microfarads to Farads (100/1,000,000=0.0001F) Then multiple this by 12V to see it stores a charge of 0.0012 Coulombs. If we needed to store a charge of say 0.0002 coulombs then we just divide this by the voltage, in this case 12V to see we need 0.0024 Farads or 2,400uF microfarads.
For most applications, the farad is an impractically large unit of capacitance. Most electrical and electronic applications are covered by the following SI prefixes: A farad is a derived unit based on four of the seven base units of the International System of Units: kilogram (kg), metre (m), second (s), and ampere (A).
The greater the applied voltage the greater will be the charge stored on the plates of the capacitor. Likewise, the smaller the applied voltage the smaller the charge. Therefore, the actual charge Q on the plates of the capacitor and can be calculated as: Where: Q (Charge, in Coulombs) = C (Capacitance, in Farads) x V (Voltage, in Volts)
Capacitance is defined as being that a capacitor has the capacitance of One Farad when a charge of One Coulomb is stored on the plates by a voltage of One volt. Note that capacitance, C is always positive in value and has no negative units.
