voltaic, a.1|vɒlˈteɪɪk|
[From the name of the Italian physician and scientist, Alessandro Volta (1745–1827) + -ic.]
1. Of apparatus: Used in producing electricity by chemical action after the method discovered by Volta; esp. voltaic battery (battery 10), voltaic pile (pile n.3 5).
(a)1813Sir H. Davy Agric. Chem. (1814) 41 It has been shown by Experiments made by means of the Voltaic battery..that compound bodies in general are capable of being decomposed by Electrical powers. 1850Grove Corr. Phys. Forces (ed. 2) 81 A voltaic battery, which consists usually of alternations of two metals, and a liquid capable of acting chemically upon one of them,..is incapable of acting. 1879G. B. Prescott Sp. Telephone 1 When galvanism was discovered, at the beginning of the present century, and the voltaic battery invented.
(b)1815J. Smith Panorama Sci. & Art II. 275 The Voltaic pile, as well as the battery last described, are now but little used. 1839Noad Electricity iii. 97 To Volta's experiments we are indebted for the first galvanic instrument, namely, the voltaic pile; it was described by him in the Philosophical Transactions of 1800. 1896Allbutt's Syst. Med. I. 352 After the discovery of the voltaic pile the use of the electrical machine gradually fell into disuse.
(c)1812Sir H. Davy Chem. Philos. 54 Without the Voltaic apparatus, there was no possibility of examining the relations of electrical polarities to chemical attractions. 1827Faraday Chem. Manip. xvii. 460 Voltaic arrangements, consisting of a few large plates rather than many small ones. 1855Bain Senses & Int. i. ii. §22 In a voltaic cell, an energy is generated and transmitted along a wire with inconceivable rapidity. 1884Knight Dict. Mech. Suppl. 930/2 A voltaic pencil, by the use of which designers and draughtsmen may be enabled to dispense entirely with the aid of the engraver.
2. Of electricity: Generated by chemical action.
1816Accum Chem. Tests 223 When the precipitation of the metallic lead takes place in the surface of the zinc, voltaic electricity is evolved. 1836M. Somerville Connex. Phys. Sci. (ed. 3) xxviii. 305 Voltaic electricity is of that peculiar kind which is elicited by the force of chemical action. 1890Nature 4 Sept., The application of voltaic electricity to the welding and fusion of metals.
b. Of a current: Consisting of voltaic electricity.
1834M. Somerville Connex. Phys. Sci. xxxi. 324 The magnetic and electric fluids,..arising from all possible positions of the conducting wire, and every direction of the voltaic current. 1860Piesse Lab. Chem. Wonders 180 The effect of a continued voltaic current.
3. Of or pertaining to, connected with, caused by, electricity due to chemical action.
1820Faraday Exp. Res. (1859) 65 The little bars..evidently produced voltaic action. 1827― Chem. Manip. xvii. 461 This formed a voltaic combination with the platina and the fluid. 1855Bain Senses & Int. ii. ii. §23 The voltaic shock is very different, in consequence of the altered character of the discharge. 1879Cassell's Techn. Educ. IV. 309/1 The invention of voltaic deposition..created a new era for the manufacture of silver-plated wares.
b. voltaic brass, brass deposited by the action of electricity.
1860Ure's Dict. Arts (ed. 5) II. 94 Voltaic brass does not appear to have been obtained in a solid distinct form, but has been successfully produced as a coating upon a copper surface.
c. fig.
1920D. H. Lawrence Lost Girl iii. 45 A superhuman, voltaic force filled her.
Hence volˈtaically adv., by means of, in respect of, voltaic electricity; after the manner of a voltaic battery.
1843Grove Corr. Phys. Forces etc. (1874) 303 Besides employing the usual chemical tests, I analysed it voltaically. 1844Noad Electricity (ed. 2) 144 When a series of some hundred couples of zinc and copper cylinders are arranged voltaically, and charged with common water, a battery is obtained. 1865Mansfield Salts 12 One of these, the Chlorine, is said to be voltaically or chemically negative. |
