Energy storage in a capacitor is a function of the voltage between the plates, as well as other factors which we will discuss later in this chapter. A capacitor''s ability to store energy as a function of voltage (potential difference between the two leads) results in a tendency to try to maintain the voltage at a constant level.

How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.

21.6: DC Circuits Containing Resistors and Capacitors
RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from …

8.2: Capacitors and Capacitance
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge
What happens if I connect a low voltage rated capacitor to a high voltage?
per @andy and predicted by @user44635 the capacitor will fail when the voltage is raised beyond some limit. The way it fails and effects thereof depend on . the failure voltage, energy stored ($frac{1}{2}CV^2$ at time of failure), rate of change in charge and voltage, type of capacitor, material and manufacturing defects,

What does the Voltage Rating on a Capacitor Mean?
The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain ...

If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

A capacitor in a DC circuit is equivalent to an open-circuit. Equation 5 indicates that the voltage across a capacitor depends on the history of the current through it. To calculate that voltage, it is necessary to know the initial voltage V o (i.e., an initial condition) across the capacitor at some previous time t o. Then:
