But the most copper money has been saved literally tens of millions of dollars by persuading thin wires to work as efficiently as thick ones. This has been done by making better transmitters, by insulating the smaller wires with enamel instead of silk, and by placing coils of a certain nature at intervals upon the wires.
Of visitors by profession. Its inconveniences. The literary character is reproached with an extreme passion for retirement, cultivating those insulating habits, which, while they are great interruptions, and even weakeners, of domestic happiness, induce at the same time in public life to a secession from its cares, and an avoidance of its active duties.
Charley suggested insulating him unawares, and getting a flash out of his knuckles, if not out of his brain. In truth, it was piteous to see the struggle between passion and nervousness that raged perpetually within him.
I have stretched across the room two ordinary cotton covered wires, each about 7 metres in length. They are supported on insulating cords at a distance of about 30 centimetres. I attach now to each of the terminals of the coil one of the wires and set the coil in action.
The tube of the coherer is generally of glass but any insulating substance will do; a wire enters at each end and is attached to little blocks of metal which are separated by a very small space. It is into this space the filings are loosely filled.
If the energy of the electrons is sufficient, these electrons will in fact rush forth and be propagated in the air or in the insulating medium interposed; but the phenomena of the discharge will in general be very complex.
They were the forest sounds of branch or tree rubbing one another, but which needed the corrective medium of daylight to convince any human that they were other than ghostly. Then, despite the wind and despite the changing murmur of the brook, there seemed to be a silence insulating them, as deep and impenetrable as the darkness.
As we shall see from what follows, however, Gray had not as yet determined that certain substances will conduct electricity while others will not. But by a lucky accident he made the discovery that silk, for example, was a poor conductor, and could be turned to account in insulating the conducting-cord. A certain Mr.
This terminal must be well insulated from the metal tube S, therefore, if the cement used is conducting and most generally it is sufficiently so the space between the plug P and the neck of the bulb should be filled with some good insulating material, as mica powder.
Ordinarily the air between the gold leaves is insulating. Bringing something radioactive near them renders the air a good conductor and the leaves fall under the radiation." "Wonderful!" I exclaimed, marveling at the delicacy of it. "Take radium water," he went on, "sufficiently impregnated with radium emanations to be luminous in the dark, like that water of Denison's. It would do the same.
