1800年,伏打用锌片与铜片夹以盐水浸湿的纸片叠成电堆,这种装置可以产生电流,后来被称为伏打电堆。伏打还制作了一种被称为“杯冕”的装置。将锌板和铜板放在盛有盐水或稀酸的杯中, 只要用导线把两种金属板连接起来,就有电流产生。他把这种装置称为“人造电器官”,与电鳗的自然电器官相对应。伏打电堆的发明,使人们第一次获得比较强且稳定而持续的电流,为电学研究奠
In 1800, Volt stacked a stack of pieces of paper soaked in salt water with zinc sheets and copper clips. This device could generate electricity and was later called a voltaic stack. Volta also made a device known as the “cup”. When the zinc plate and the copper plate are placed in a cup filled with salt water or dilute acid, an electric current is generated by connecting the two metal plates with wires. He called this device an “artificial electrical organ,” which corresponds to the natural electrical organs of the eel. The invention of the voltaic reactor has enabled people to obtain a relatively strong and stable current for the first time.
