What is a Decoupling Capacitor?
In electronic circuits, it is often seen that there is an electrolytic capacitor near the power supply pins of the integrated circuit. This capacitor is a decoupling capacitor. Decoupling capacitors usually have two functions: one is energy storage, and the other is to remove high-frequency noise.
How do I know the maximum voltage that a capacitor releases?
Capacitors store energy. The voltage depends upon the amount of charge and the size of the capacitor. (Q = CV, Energy stored = 0.5CV^2). If you connect a resistor across the terminals of a charged capacitor an initial current (= V/R) will flow but this will rapidly fall towards zero as the capacitor is discharged. ...
