Units of capacitance measure the ability of a system to store electrical charge per unit voltage. The standard unit of capacitance is the Farad (F), named after the physicist Michael Faraday. One Farad represents the capacitance of a system when a one-volt potential difference (voltage) results in the storage of one coulomb of electrical charge.
Equation 1 is the required formula for calculating the capacitance of the capacitor and we can say that the capacitance of any capacitor is the ratio of the charge stored by the conductor to the voltage across the conductor. Another formula for calculating the capacitance of a capacitor is, C = εA / d
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)
Answer: The SI unit to measure the capacitance of any material is Farad, denoted as F. The farad is a very big unit of capacitor, so the most common unit of capacitance is μF (10-6 F), or nF (10-9F).
We now know that the ability of a capacitor to store a charge gives it its capacitance value C, which has the unit of the Farad, F. But the farad is an extremely large unit on its own making it impractical to use, so sub-multiple’s or fractions of the standard Farad unit are used instead.
Since capacitance is the charge per unit voltage, one farad is one coulomb per one volt, or 1F = 1C 1V. By definition, a 1.0-F capacitor is able to store 1.0 C of charge (a very large amount of charge) when the potential difference between its plates is only 1.0 V. One farad is therefore a very large capacitance.
