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. For example, energy is transferred from a power source to an electrical load by means of conductive coupling, which may be either resistive or direct coupling. An AC potential may be transferred from one circuit segment to another having a DC potential by use of a capacitor. Electrical energy may be transferred from one circuit segment to another segment with different impedance by use of a transformer; this is known as impedance matching. These are examples of electrostatic and electrodynamic in

| - 在电子学和电信领域，耦合（英語：coupling）是指能量从一个介质（例如一个金属线、光导纤维）传播到另一种介质的过程。 在电子学中，耦合指从一个电路部分到另一个电路部分的能量传递。例如，通过电导性耦合（ Conductive coupling），能量从一个电压源传播到负载上。也可以利用电容器允许通过交流成分、阻挡直流成分的性质，可以将电路的交流部分和直流部分耦合起来。若要將電能轉換到另一個不同阻抗的電路，也可以透過变压器來進行，這稱為阻抗匹配。這些是电容耦合或是電動感應耦合的例子。 (zh)

- In elettrotecnica, l'accoppiamento consiste nel trasferimento di energia elettrica da un sistema ad un altro. Tale trasferimento può essere desiderato o no, nel secondo caso si parla di effetti parassiti. Può essere ottenuto mediante:
* accoppiamento conduttivo - tramite contatto fisico;
* accoppiamento induttivo - tramite induzione elettromagnetica;
* accoppiamento capacitivo - tramite induzione elettrostatica;
* accoppiamento acustico;
* accoppiamento ottico, ad esempio mediante optoisolatore;
* accoppiamento elettromeccanico;
* accoppiamento elettronico:
* altri tipi di accoppiamento. (it)
