Ultracapacitors and the Ultracapacitor Battery
Where: Q (Charge, in Coulombs) = C (Capacitance, in Farads) times V (Voltage, in Volts) The unit of capacitance is the coulomb/volt, which is also called the Farad (F) [named after M. Faraday] with one farad being defined as the capacitance of a capacitor, which requires a charge of 1 coulomb to establish a potential difference of 1 volt between its two plates.
