 * What is the most important invention to use elecricity in the 19th Century?**

I think the most important invention to the use electricity is the battery. The first battery was invented by Alessando Volta in 1800. How the battery worked is by alternating discs of zinc and copper with cardboard pieces soaked in brine between the metals, voltic pile produced electric currents, then a metallic ark carried electricity over a great distance.Why I think the battery is the most important invention to use electricity in the 19th century is because the battery help invent rechargeable batteries. Without rechargeable batteries we would not be able to use laptops, ipods, cell phones, DS, PSP, Game Boy SP, and more without using larger batteries that die faster then rechargeable battery.
