The standard volt, and sub-standards for the measurement of pressure from 25 to 3000 volts.
The electrical pressure required to force a current of this intensity through the solution, and to overcome a certain opposing electromotive force arising from the more electro-negative impurities of the anode, depends upon the composition of the bath and of the anodes, the distance between the electrodes, and the temperature, but under the usual working conditions averages o-3 volt for every pair of electrodes in series.
With too% currentefficiency and a potential difference of 0.3 volt between the electrodes, t lb of copper should require about o-154 electrical horse-power hours as the amount of energy to be expended in the tank for its production.
A pressure of 1.5 volt usually suffices when the space between the electrodes is 2 in.
Having by a fresh volt e-f ace passed into alliance with Great Britain, Louis *V.s government accepted an alliance with Maria Theresa in the treaty of the 1st of May t756.
Between parts of the same metal at different temperatures, but the difference would probably be of the order of only one-hundredth of a volt for a difference of too° C. It would be sufficiently difficult to detect so small a difference under the best conditions.
Currents from the ten-thousandth of an ampere to ten thousand amperes, electrical pressures from a minute fraction of a volt to 100,000 volts, come within the range of his instruments, while the private consumer of electric energy is provided with a meter recording Board of Trade units.
He is celebrated as a pioneer of electrical science, after whom the "volt" is named.
This Volt-Wheel has been around a half dozen years.
The radioactivity is denoted by A, and A = signifies that the potential of the dissipation apparatus fell I volt in an hour per metre of wire introduced.
The instant cries of Deus volt which answered the note showed that Urban had struck aright.
Louis receives 70,000 H.P. by a Iio,000-volt transmission line from the Keokuk dam in the Mississippi at Keokuk, Ia.
52 volt, and observed as 0.51 volt.
If, instead of using a single Daniell's cell, we employ some source of electromotive force which can be varied as we please, and gradually raise its intensity, we shall find that, when it exceeds a certain value, about 1.7 volt, a permanent current of considerable strength flows through the solution, and, after the initial period, shows no signs of decrease.
The opposing force of polarization is about 1.7 volt, but, when the plates are disconnected and used as a source of current, the electromotive force they give is only about 1.07 volt.
If the plates be covered with a deposit of platinum black, in which the gases are absorbed as fast as they are produced, the minimum decomposition point is 1.07 volt, and the process is reversible.
When H =2000 is of the order of 1/100 volt for iron, I/IOoo volt for nickel and I/Io,000 for bismuth.
Van, " is "; vannak, " are "; volt, " was"; lesz, 1 See Hunfalvy's " Die ungarische Sprachwissenschaft," Literarische Berichte aus Ungarn, pp. 80-87 (Budapest, 1877).
Nekem vannak kOnyveim, literally, " to me are books-my " = " I have books "; neki volt konyve, " to him was book-his "=" he had a book."
(b) In lieu of oil-lamps, small, conveniently placed incandescent electric 6-volt lamps are employed; and these are fitted with suitable switches and variable resistances.
981 volt, the strip difference having a resistance of 0.1 ohm, it would be seen that the current passing through the strip was 98 I amperes.
Sumpner in 1891, an electrostatic voltmeter is employed to measure the fall of potential V 1 down any inductive circuit in which it is desired to measure the power absorption, and also the volt-drop V2 down an inductionless resistance R in series with it, and also the volt-drop V3 down the two together.
The charge was reduced by means of a 50-volt current from a Soo-kilowatt dynamo, which was passed through the furnace for 12 hours till decomposition was complete.
The disadvantage is that the thermo-electric force is very small, about ten-millionths of a volt per degree, so that a small accidental disturbance may produce a serious error with a difference of temperature of only 1° between the junctions.
