Men like Ohm and Maxwell have reduced electricity to a mathematical science, and it is by accepting, mastering, and applying the laws of electric currents which they discovered and expounded that the electric light, electric railway, and all other applications of electricity have been developed.
He caught himself up, but after the slightest pause, resumed: "Forsan et haec ohm meminisse juvabit. Look at Clive, I was saying; a lout, a bear, a booby as a boy, mark you; yet now! Is there a man whose name rings more loudly in the world's ear? And what Robert Clive is, that Desmond Burke might be if he had the mind and the will. You are going farther? Ah, I have not your love of ambulation.
Thus, Ohm, who has worked particularly in the reduction of the increased tension of secondary glaucoma, for example, after discussion of lamellar cataract, advocates the Piesbergen instrument, which makes 3,000 vibrations a minute, and is applied over the closed lids. I think the instrument best known is the one introduced by Malakow.
The unit of electromotive force is the volt, and this is the electric pressure which will force a current of 1 ampere through a resistance of 1 ohm; it is expressed by the symbol E. A fresh dry cell will deliver a current of about 1.5 volts. Resistance and the Ohm.
S. W. Christie, of the Royal Military Academy, Woolwich, who published it in the PHILOSOPHICAL TRANSACTIONS for 1833. The method was neglected until Wheatstone brought it into notice. His paper abounds with simple and practical formula: for the calculation of currents and resistances by the law of Ohm.
Each box measured about 18 in. by 12 in. by 10 in., and weighed from 75 lb. to 100 lb. The electromotive force of each cell was 1.8 volts and its internal resistance from 1/40 to 1/50 of an ohm, consequently the battery exhibited had, under the must favorable circumstances, a difference of potential of 27 volts at its poles, and a resistance of 0.3 ohm.
S.K. Dingle, proceeded to that town with a receiving instrument, and we made the first test. I found that 800 words, or 20,000 impulses, per minute, could be transmitted in Morse characters over that circuit without compensation for static. In other words, the old Bain method was competent to telegraph 800 words per minute on the 400 miles of 1.5 ohm wire.
M. Righi has ably demonstrated that ionised gas does not obey the law of Ohm by an experiment very paradoxical in appearance. He found that, the greater the distance of the two electrode plates from each, the greater may be, within certain limits, the intensity of the current.
If we speak of the propagation of a current in a material medium, can one forget the names of Fourier and of Ohm, who established by theoretical considerations the laws which preside over this propagation? When one looks at the phenomena of induction, would it not be just to remember that Arago foresaw them, and that Michael Faraday discovered them?
"Some careful experiments on the decomposing power at various distances were made from which the law of propulsion has been deduced, verifying the results of Ohm and those which I made in the summer of 1842, and alluded to in my letter to the Honorable C.G. Ferris, published in the House Report, No. 17, of the last Congress.
