The voltaic pile was the first electric battery, and, therefore, the parent of the existing marvellous telegraphic and telephonic systems, while less immediately it led to the development of the dynamo and its work in electric lighting and traction.
But from all these difficulties emerged the golden truth, that under every variety of circumstances the decompositions of the voltaic current are as definite in their character as those chemical combinations which gave birth to the atomic theory. This law of Electro-chemical Decomposition ranks, in point of importance, with that of Definite Combining Proportions in chemistry.
Davy, of the safety-lamp, threw a volume of current across the gap between two sticks of charcoal, and the voltaic arc, forerunner of electric lighting, shed its bright beams upon a dazzled world. The decomposition of water by electrolytic action was recognized and made the basis of communicating at a distance even before the days of the electromagnet.
Origin of power in the voltaic pile. In one of the public areas of the town of Como stands a statue with no inscription on its pedestal, save that of a single name, 'Volta. The bearer of that name occupies a place for ever memorable in the history of science. To him we owe the discovery of the voltaic pile, to which for a brief interval we must now turn our attention.
His first inventions in the art, made in 1875-76, continue through many later years, including all kinds of carbon instruments the water telephone, electrostatic telephone, condenser telephone, chemical telephone, various magneto telephones, inertia telephone, mercury telephone, voltaic pile telephone, musical transmitter, and the electromotograph. All were actually made and tested.
The character of the electricity is precisely the same as that generated in the voltaic battery.
On sending the voltaic current through the solution, the lead will be slowly severed from the atoms with which it is now combined; it will be liberated upon one of the wires, and at the moment of its liberation it will obey the polar forces of its atoms, and produce crystalline forms of exquisite beauty.
The town is strewn with our shell and shot, etc. We have traced voltaic wires to nearly every powder magazine in the place. What plucky troops they were! When you hear the details of the siege you will be astonished. The length of the siege is nothing in comparison with our gain in having destroyed the place.
He became acquainted with the voltaic battery through the lectures of his friend, Professor Sieliman; and we are told that during one of his vacations at Yale he made a series of electrical experiments with Dr. Dwight.
The torpedo moves the pectoral fins convulsively every time it emits a stroke; and this stroke is more or less painful, according as the immediate contact takes place by a greater or less surface. We cannot discharge at will either a torpedo or a gymnotus, as we discharge at will a Leyden jar or a Voltaic battery. A shock is not always felt, even on touching the electric fish with both hands.
