What is Reciprocity Theorem? - explanation with circuit diagram ...
Reciprocity Theorem states that – In any branch of a network or circuit, the current due to a single source of voltage (V) in the network is equal to the current through that branch in which the source was originally placed when the source is again put in the branch in which the current was originally obtained. This theorem is used in the ...

在电磁学上，互易定理为洛仑兹互易定理（Lorentz Reciprocity Theorem）,由卡森（J.R. Carson）导出而被称为卡森形式的互易定理。 互易定理可以利用 麦克斯韦方程 得到。 设空间有两组源J1和J2，分别产生的场为E1、H1和E2、H2，如图4所示. (1)两个电流源J1和J2均在空间区域V外。 (2)当V表示整个空间区时，S为无限大闭合面S∞。 上式称为称为卡森互易定理。 [2] 源传互易原理支持者的依据主要有二：一是所谓的热力学证明，这已被证明为误；另一依据则可以简 …

在 电磁学 中， 互易定理 是 电磁场 理论的重要定理。 由 洛伦兹 首先发现了一个定义在闭合曲面上的电磁场公式。 后来Rayleigh-Carson又进一步把定理发展称为我们今天看到的形式，定义在一个体积分上。 都是由曲面内的电流元产生的辐射场。 这里假定计算是在频域或者傅里叶变换域。 我们在电磁场公式中省写了. 洛伦兹发现如下形式的互易定理. 注意：上面强调两个电磁场都是辐射场，其实是说这两个场都必须是 滞后波。 如果其中一个是 超前波，一个是滞后波上述曲面积 …
Reciprocity (electrical networks) - Wikipedia
Reciprocity in electrical networks is a property of a circuit that relates voltages and currents at two points. The reciprocity theorem states that the current at one point in a circuit due to a voltage at a second point is the same as the current at the second point due to the same voltage at the first.
Reciprocity Theorem - Electrical4U
2012年2月24日 · Reciprocity Theorem Definition: The reciprocity theorem states that in a reciprocal circuit, the current remains the same when the positions of the voltage source and ammeter are swapped. Reciprocal Circuit : A circuit that follows the reciprocity theorem, where voltage and current are interchangeable, is called a reciprocal circuit.
The reciprocity theorem states that if a voltage source is applied to either port 1 or 2 of this network, it will produce the same short circuit current in the other port. That...
reciprocity theorem. Circuit relationship is possible when the ports of the antennas are small compared to wavelength. The reciprocity theorem can be used to distill and condense the interaction between two antennas over a complex terrain as long as the terrain comprises reciprocal media. In Figure 30.4, we assume that antenna 1 is driven by ...

由诺特定理可知，每个连续对称性都对应着相应的守恒定律，即 对称意味着守恒。 对称是物理学中非常重要的概念与意识，很多重大发现都与此相关。 互易定理是表示定理的基础，其和Green's function结合就能推导出表示定理，在互易定理中需注意： 1）互易定理在两个体系交集部分成立；2）与时间无关（第一互易定理）。 互易定理可简单理解为第一组力在第二组力产生位移上做的功等于第二组力在第一组力产生位移上做的功，这个功包括体力，面力与惯性力所做的功。 …
Reciprocity Theorem: Know Statement, Circuit Diagram
2024年9月23日 · Reciprocity theorem is a fundamental principle in electrical engineering that relates to the behaviour of linear, passive, and bilateral circuits. It states that the ratio of the voltage across a given element to the current through another element in a circuit remains unchanged when the positions of these elements are interchanged.

The Lorentz reciprocity theorem (Equation \ref{m0214_eLRTI2}) describes a relationship between one distribution of current and the resulting fields, and a second distribution of current and resulting fields, when both scenarios take place in identical regions of space filled with identical distributions of linear matter.
