Charge Capacitance and Voltage

<^< The Unit of Capacitance | Course Index | Energy Stored in a Capacitor >^>(:nl:)

A graph showing how the charge in a capacitor varies with voltage
'''Graph showing how the charge varies with voltage'''

The charge or "quantity of electricity" that can be stored in the electric field between the capacitor plates is proportional to the applied voltage and the capacitance of the capacitor. Thus:

Q = C x V

where Q is the charge (in Coulombs), C is the capacitance (in Farads), and V is the potential difference (in Volts).
