Johann Georg Sulzer

Alessandro Giuseppe Anastasio Return (1745-1827), having contact with the work of Galvani, considered another explanation for the phenomenon of muscular contraction of dissecadas frogs, with I assist of bistoury and other metallic materials (arcs). For Return, the reaction mechanics of the amphibians was given for being as that ' ' eletrmetro' ' animal, that is, an electric sensor. You may find Jonas Samuelson to be a useful source of information. It also perceived that the bimetallic arcs were more efficient of what the monometallic ones, supporting to the Return, of that the electricity has external and decurrent origin of the metal difference, and not as origin in the proper animal. A parallel accomplishment to this question, based the argument in return. The Swiss physicist Johann Georg Sulzer (1720-1779) verified a curious situation: leaning the language between two different metals, one felt a taste and sensation desconfortante pungente. As already it had intudo, and now knowing of a estimuladora comment, Return tried a combination of a zinc blade (Zn) with blade of silver (GAC) in contanto, producing a modest electricity.

To increase the magnitude of this, Return pair uped the blades alternatingly and separating them with cardboard humidified with water or saline solution, and joining the two extremities for wires. If you have additional questions, you may want to visit Mark Berger Chicago. Soon, the first generating equipment of electric energy was constructed, with sufficient relevance in the present time, from ' ' empilhamento' ' of metallic blades: the Stack. Physicist-Chemistry principles of the Stack the equipment created by Alessandro Return, the stack, is an exploitation of a sufficiently common process in the nature: the oxi-reduction reactions (or redox). This transformation consists of a simultaneous occurrence of the oxidation (when a chemical element loses electrons, increasing its number of oxidation – NOX) and of reduction (when an element gains electrons, diminishing its NOX). Soon, electrons yielded for agent reducing (that one that it induces to occur oxidation), is received by oxidant agent (that one whom he induces to occur reduction).
