couˈlometer
[refashioning of coulomb-meter.]
= coulomb-meter; voltameter.
1902Richards & Heimrod in Proc. Amer. Acad. Arts & Sci. XXXVII. 415 The word ‘voltameter’ was devised before electrical dimensions were understood. It is moreover too much like the universally used..word ‘voltmeter’. Now that the former instrument is placed upon a firm basis of accuracy, it may appropriately receive also an accurate name; and it is hoped that the new word ‘coulometer’ may replace wholly the anachronism. 1925M. de K. Thompson Theor. & Appl. Electrochem. i. i. 6 In any coulometer the current can be computed from the quantity of electricity that has passed through the circuit, if the current has been constant and if the time is measured. 1943Gloss. Terms Electr. Engin. (B.S.I.) 73 Coulometer, an electrolytic cell serving to measure a quantity of electricity by the amount of a substance which is liberated electro-chemically: measured either by weight as in a weight coulometer, or by volume as in a volume coulometer. |
