occurs when a capacitor or an inductor is connected, via a switching event, to a circuit that contains only an equivalent resistance (i.e., no independent sources). In that case, if the capacitor is initially charged with a voltage, or the inductor is initially carrying a current, the capacitor or inductor will release its energy to the resistance.
A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure (PageIndex{1}).

Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V.If the charge changes, the potential changes correspondingly so …
voltage and load current. A constant current (CC) converter regulates current the same way: the control loop adjusts the duty cycle to maintain a constant output current regardless of changes to the input voltage and output resistance.
