简单的伏打电池并不能供给一个稳定电流。这是因为在正极板上面有氢气泡的聚集,只要你把它们刷去的话,电流就复原了。假如你使电池停止放电,气泡最后也会消失,那末电池也就复原。这就是何以伏打对于他的电堆和电杯,在手触它们的时候,看上去有如同来顿瓶一般的放电,后来却又很神秘地会自己重新充电的。人体的电阻极高,所以电池所能输出通过人体的电流是很小的,电解质中的化学作用也是很小的,这便是何以在化学材料消耗尽了以前,这样的充电和放电能够继续一个长的时期的原故。英国牛津大学的克来仑顿实验室,在1840年,装成了一个电堆,自从那时候起便敲击着一对的
A simple voltaic battery does not provide a stable current. This is because of the accumulation of hydrogen bubbles on the positive plate. The current is restored as long as you brush them. If you stop discharging the battery, bubbles will eventually disappear and the battery will recover. This is why the volts hit his stacks and cups. When they touched them, they looked like a bottle of discharge. They mysteriously recharged themselves. The resistance of the human body is extremely high, so the current that the battery can output through the human body is very small, and the chemistry in the electrolyte is also very small. This is why the charge and discharge can continue until the chemical material is exhausted. The reason of the long period. The Kleinlunden Laboratory at Oxford University in the United Kingdom, in 1840, installed a stack, and since then it has hit a pair of
