College Physics for AP Courses 2015-08-12T00:00:00Z This approach is called agrivoltaics — a portmanteau of agriculture and voltaic cells, which transform solar power to electrical power. Can Dual-Use Solar Panels Provide Power and Share Space With Crops? 2022-06-28T04:00:00Z As a voltaic cell, then, Trump is a largely untapped resource. If Donald Trump Were Actually a Battery 2017-05-18T04:00:00Z From this result Thomson proceeded to calculate the electromotive forces required to effect chemical changes of different kinds, and those of various types of voltaic cell. Lord Kelvin An account of his scientific life and work 2012-04-06T02:00:32.097Z Electrical studies, however, engaged most of his attention, especially in connexion with the theory of the voltaic cell and the electric discharge in rarefied gases. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 10 "David, St" to "Demidov" 2012-02-17T03:00:33.923Z His researches dealt very largely with electro-chemistry and with the voltaic cell, of which he invented several varieties. Encyclopaedia Britannica, 11th Edition, Volume 12, Slice 6 "Groups, Theory of" to "Gwyniad" 2011-12-16T03:00:12.320Z The voltaic cell, on the other hand, furnishes a large quantity of electricity at low pressure, as a street may be flooded by a broken water-main though the pressure is low. The Story of Great Inventions 2011-10-05T02:00:16.353Z This kind may also be noted in the voltaic cell and the charged condenser, and in a chemical form in coal and gunpowder. The New Gresham Encyclopedia Volume 4, Part 2: Ebert to Estremadura 2011-04-14T02:00:56.200Z This condition may be realized to some extent in a manner that throws light on the general theory of the voltaic cell. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 2 "Ehud" to "Electroscope" 2011-01-29T03:00:23.777Z For several years preceding 1820, no other instrument could compare the “strengths” of two voltaic cells better than the test of the respective maximum lengths of this wire that they could heat to fusion. The Earliest Electromagnetic Instruments About 1839 he constructed the platinum-zinc voltaic cell that bears his name, and with the aid of a number of these exhibited the electric arc light in the London Institution, Finsbury Circus. Encyclopaedia Britannica, 11th Edition, Volume 12, Slice 6 "Groups, Theory of" to "Gwyniad" 2011-12-16T03:00:12.320Z The voltaic cell is the simplest form of electric battery. The Story of Great Inventions 2011-10-05T02:00:16.353Z The current from one or two voltaic cells is led to an ebonite drum turned by a motor or a hand-wheel and cord. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" Practical Application of Heat, Steam, and Electricity: Making a simple voltaic cell, an electro-magnet, and a simple electroscope. Ontario Teachers' Manuals: Nature Study In my lecture of September 16th, I showed that Oersted’s results depend, not on the voltaic cell, but only on the connecting circuit. The Earliest Electromagnetic Instruments Sorensen was absolutely correct in his statements about the state of the art of making voltaic cells. With No Strings Attached A new and theoretically interesting molecular voltaic cell may thus be made, in which the two elements consist of the same metal. Response in the Living and Non-Living At first he believed that mere contact was sufficient, but when, later, it was shown that chemical action took place, rapid progress was made in the construction of voltaic cells. Artificial Light Its Influence upon Civilization For example, the simple voltaic cell and the gravity cell have approximately equal voltages, but the current produced by the voltaic cell is stronger than that produced by the gravity cell. General Science Despite the many uses made of voltaic cells after Volta’s announcement of his “pile” invention in 1800, two decades passed before Oersted discovered the magnetic effects of a voltaic circuit. The Earliest Electromagnetic Instruments On having been verified with a standard voltaic cell the apparatus becomes itself a standard, especially for small electromotive forces. Scientific American Supplement, No. 441, June 14, 1884. The cell is then, when the charging current ceases, capable of acting as a voltaic cell. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. It was supplied with current by a large voltaic cell, but the success of the electric arc was obliged to await the development of a more satisfactory source of electricity. Artificial Light Its Influence upon Civilization The voltage of a dry cell is approximately 1.5 volts, and the voltage of a voltaic cell and of a gravity cell is approximately 1 volt. General Science This letter was written after the chemical changes in the voltaic cell had received a great deal of attention by many experimenters, the most prominent of whom was Davy. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The ordinary voltaic cell is made by bringing together certain chemicals, whose reaction maintains the electric currents taken from the cell. The Project Gutenberg Encyclopedia Volume 1 of 28 A very simple voltaic cell may be made by placing two plates, one of copper and one of zinc, in a glass vessel partly filled with dilute sulphuric acid, as shown in Fig. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. Any two of these metals constitute a voltaic cell. Man or Matter The hydrogen formed by the chemical action of the dilute sulphuric acid on the zinc moves toward the copper electrode, as in the simple voltaic cell. General Science The action of the thermo-pile, like that of a voltaic cell, can be reversed. The Story of Electricity Kelvin and Helmholtz have shown that the E.M.F. of a voltaic cell oan be calculated from the energy developed by the chemical action. The Project Gutenberg Encyclopedia Volume 1 of 28 Commercial zincs, for use in voltaic cells as now manufactured, Page 98 usually have about 4 per cent of mercury added to the molten zinc before casting into the form of plates or rods. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. He thought that with a single voltaic cell he had obtained the spark before the metals touched, but he subsequently discovered his error. Faraday as a Discoverer Zinc, in galvanizing iron, 49. in making hydrogen, 80.in voltaic cell, 307-308. General Science The electromotive force and current of a thermo-electric couple is very much smaller than that given by an ordinary voltaic cell. The Story of Electricity Just why or how chemical action in a voltaic cell results in the production of a negative charge on the consumed plate is not known. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. Each of these particles acts with the surrounding zinc just as might be expected of any pair of dissimilar elements opposed to each other in an electrolyte; in other words, they constitute small voltaic cells. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. From this series it is easy to see why zinc and copper, and also zinc and carbon, are often chosen as elements of voltaic cells. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. Becquerel, the French chemist, found that two plates of silver freshly coated with silver from a solution of chloride of silver and plunged into water, form a voltaic cell which is sensitive to light.
