Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor's ability to prevent a DC load from interfering with an AC source is particularly useful in Class A amplifier circuits by preventing a 0 volt input being passed to a transistor with additional ...
English: Schematic of a parallel plate capacitor with a dielectric spacer. Two plates with area A {\displaystyle A} are separated by a distance d {\displaystyle d} . When a charge ± Q {\displaystyle \pm {}Q} is moved between the plates, an electric field E {\displaystyle E} exists in the region between the plates.
In electronics, electric power and telecommunication, coupling is the transfer of electrical energy from one circuit to another, or between parts of a circuit. Coupling can be deliberate as part of the function of the circuit, or it may be undesirable, for instance due to coupling to stray fields .
A decoupling capacitor provides a bypass path for transient currents, instead of flowing through the common impedance. [1] The decoupling capacitor works as the device’s local energy storage. The capacitor is placed between the power line and the ground to the circuit the current is to be provided.

A common example is connecting localized decoupling capacitors close to the power leads of integrated circuits to suppress coupling via the power supply connections. These act as a small localized energy reservoir that supply the circuit with current during transient , high current demand periods, preventing the voltage on the power supply rail ...
