The instrument comprises a number of reeds of different lengths, mounted in a row, and all simultaneously subjected to the oscillatory attraction of an electromagnet excited by the supply current that is being measured.
A lightning discharge is of an oscillatory character and possesses the property of self-induction, accordingly it passes with difficulty through coils of wire.
It has been indicated that the differential equation does not represent oscillatory motion if the value of R is too great.
This process represents, according to the modern theory of the flow of energy in the electromagnetic field, with more or less accuracy, what takes place in the oscillatory discharge of a condenser.
It is more instructive perhaps to take theoscillatory motion of a spiral spring hung vertically with a weight on its lower end, as that which has a differential equation equivalent to the equation just found.
The particular case of non-oscillatory discharge obtained by supposing C and Q both infinitely great and to have a finite ratio V (which will be the potential, p.
Thomson concludes by showing how, by measuring the non-oscillatory discharge of a condenser (the capacity of which can be calculated) by means of an electrodynamometer and an ordinary galvanometer arranged in series, what W.
Thomson suggested that double, triple and quadruple flashes of lightning might be successive flashes of an oscillatory discharge.
For such vibrators are really Leyden jars, or condensers, caused to discharge in an oscillatory manner.
The two coatings and the wire form what is called an oscillatory circuit.
After much experimenting Hertz, of Carlsruhe, discovered the fact that when a discharge was taking place in an oscillatory circuit tiny sparks passed between the ends of a curved wire held some distance away.
And there we have quite a good oscillatory circuit.
Those of a very rapid oscillatorycharacter were especially numerous in the morning between 4 and 9 a.
Two small handles depend from the needle bar, by which the oscillatory motion upon the upper centres is given.
They are also screwed to a bar of iron, generally lighter than the other, and secured by means of plates: this bar is not fixed, but has a pivot in each end, by means of which the bar may have a kind of oscillatory motion on these pivots.
The hairspring takes up the shock of this intermittent motion and a balance wheel carried by the staff to which F is fastened steadies the oscillatory motion of the lever D.
The reason for this is that the water in the waves does not travel with the waves, but undergoes local oscillatory motion.
Each particle of air has a local oscillatory motion which it communicates to its neighbor, producing alternate compression and rarefication, and it is this wave action that travels through the column.
The closed oscillatory circuit consists of an inductance F, spark-gap G, and a block condenser C.
In this manner they restore the equilibrium of the oscillatory motions, which establish the tone of the nervous system.
An oscillatory current of high potential is produced in a circuit which consists of rapidly rotating disks in connection with the dynamo and suitable condensers.
This discharge, however, is not a single movement of electricity in one direction but an oscillatory motion with gradually decreasing amplitude.
He confirmed an opinion already previously expressed by Helmholtz and by Henry, that in some circumstances this discharge is oscillatory in nature, consisting of an alternating electric current of high frequency.
If the oscillatory spark is photographed on a revolving plate or a rapidly moving film, we have evidence in the photograph that such a spark consists of numerous intermittent sparks gradually becoming feebler.
In the sensitive silver cell, we found that the molecular strain produced by light gave rise to a current of response, and that on the cessation of light an oscillatory after-effect was produced.
The alternate fluctuations become far more conspicuous when the eyes are closed; the pure oscillatory after-effects are then obtained in a most vivid manner.
If there has been a feeble initial current, this oscillatory after-current, by algebraical summation, will cause the current in the circuit to be alternately weaker and stronger than the initial current.
The discharge circuits, which may take the shape of bulbs, or of tubes bent in the form of coils, were placed in close proximity to glass tubes filled with mercury, which formed the path of the oscillatory discharge.
It seems highly probable that light, too, is not a special form of energy, but a peculiar oscillatory combination of electrical and magnetic energies.
Radiant energy is characterized as an oscillatory or wave-like process.
The duration of the elementary oscillation remaining the same, the absolute velocity of the ethereal particles, at the corresponding periods of the oscillatory motions, is, as we have seen, proportional to its extent.
It is shown by calculation, that the amplitude of the oscillatory motion, or the absolute velocity of the particles concerned in it, is inversely proportional to the distance from the centre of agitation.
This plough was preferred in the beds and gravelly grounds; and it was found advantageous to give it an oscillatory movement by the handles during its progress.
Defn: A disruptive discharge between a conductor traversed by an oscillatory current of high frequency (as lightning) and neighboring masses of metal, or between different parts of the same conductor.
An advancing ridge or swell on the surface of a liquid, as of the sea, resulting from the oscillatory motion of the particles composing it when disturbed by any force their position of rest; an undulation.
An oscillatory spark discharge started off with a roar in a closed box, and the coil of wire became white hot.
You know about Hiroshito's experiments, of course; he used a quartz bulb containing a mixture of neon gas and the vapour of mercury, placed at the centre of a coil of silver wire carrying a big oscillatory current.
It would thus appear that periodic phenomena may be propagated through space without vibratory or oscillatory motion.
