When a potential of appears across a capacitor, the capacitor's plates have a charge of magnitude 5.0 5. If the potential is changed to 36 what is the new charge on the capacitor plates? This energy can be used to power electrical components when the capacitor is discharged.
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
The voltage between the plates and the charge held by the plates are related by a term known as the capacitance of the capacitor. Capacitance is defined as: The larger the potential across the capacitor, the larger the magnitude of the charge held by the plates.
The charge of a capacitor is directly proportional to the area of the plates, permittivity of the dielectric material between the plates and it is inversely proportional to the separation distance between the plates.
The plates will hold equal and opposite charges when there is a potential difference between them. Figure 1: A capacitor with a voltage V across it holding a charge Q. In practice this means that charges +Q and −Q are separated by the dielectric.
When a DC voltage is placed across a capacitor, the positive (+ve) charge quickly accumulates on one plate while a corresponding and opposite negative (-ve) charge accumulates on the other plate. For every particle of +ve charge that arrives at one plate a charge of the same sign will depart from the -ve plate.
