The Electric Pickle

电荷的腌黄瓜

Thanks to Brian Lucy for this example.
感谢Brian Lucy提供的这个例子。

A far-fetched example of a non-ohmic resistor is the electric pickle. A considerable amount of light can be obtained by connecting ordinary household 120 volt AC voltage across a pickle. After the pickling process, there are Na+ and Cl- ions present. The standard explanation is that the electric current excites the sodium ions, producing light similar to that of a sodium lamp.

一个非欧姆电阻的荒谬例子是电瓶。通过将普通的家庭120伏交流电压加在电瓶上，可以得到相当多的光。在腌制过程之后，存在Na+和Cl-离子。标准的解释是，电流激发钠离子，产生类似于钠灯的光。

Currents in ionic solutions are often not linearly proportional to the applied voltage. When Ohm's law is used with ordinary carbon resistors, the ratio of voltage to current is constant, but the variation in light output suggests that this is not the case with the electric pickle.

离子溶液中的电流往往并不与施加的电压成线性比例。当使用普通碳电阻时，电压与电流的比值是恒定的，但光输出的变化表明这在电灯泡的情况下并不成立。

Caution! Potentially lethal shock hazard! Because of the use of exposed bare wires in this demonstration, it should be done with great care and capable supervision.

注意！可能致命的触电危险！由于本演示使用了裸露的导线，因此必须谨慎操作，并在有监督的情况下进行。
