Since a capacitor is a "container" for storing charge, there is a problem with the size of the "capacity". To measure the capacity of a capacitor to store charge, the physical quantity of capacitance is determined. The capacitor must be able to store charge under the influence of an applied voltage. The amount of charge stored by different capacitors under voltage may also be different. In addition to the voltage effect, the capacitance is also affected by factors such as operating frequency and temperature.
