Squeezing the same charge into a capacitor the size of a fingernail would require much more work, so V would be very large, and the capacitance would be much smaller. Although the equation C = Q / V C = Q / V makes it seem that capacitance depends on voltage, in fact it does not. For a given capacitor, the ratio of the charge stored in the capacitor to the voltage … - Download [PDF]

Capacitors used within high energy capacitor banks can violently explode when a fault in one capacitor causes sudden dumping of energy stored in the rest of the bank into the failing unit. And, high voltage vacuum capacitors can generate soft X-rays even during normal operation. Proper containment, fusing, and preventative maintenance can help to minimize these hazards.

The Capacitor. A capacitor is a device that consists of two parallel metallic plates placed extremely close to one another. The primary objective of a capacitor is to store charge. The charge can later be released to drive other circuits. This property renders it very useful in devices such as inverters. However, before releasing charge, it ...

However, the potential drop (V_1 = Q/C_1) on one capacitor may be different from the potential drop (V_2 = Q/C_2) on another capacitor, because, generally, the capacitors may have different capacitances.
