Electrons prised from those ions make a similar journey, but do so in an external circuit, usually through a wire.

与这些离子相匹配的电子走的是类似旅途，但是穿过的却是外部电路，通常是一根电线。

In other words, the circuit may be physical two - wire (or even physical one - wire) and logical four - wire, performing as a four - wire circuit but employing fewer than four wires.

换句话说，电路可以是物理双线(甚至是物理单线)、逻辑四线，它使用较少的线实现四线电路。

To compensate for this movement of ions, electrons have to move in the opposite direction and if the electrodes are connected by a conducting wire running through a useful circuit, that is the route they will take.
