If we consider a simple circuit in which a current is flowing, and include in the circuit a carbon horseshoe-like conductor which it is desired to bring to incandescence by the heat generated by the current passing through it, it is first evident that the resistance offered to the current by the wires themselves must be less than that offered by the burner, because, otherwise current would be wasted as heat in the conducting wires.
Sandford, you said a word just now I did not understand." "Only one?" said the doctor. "I think there was only one I did not know in the least." "Can you direct me to it?" "You said something about an ocean of air in a state what state?" "Incandescence?" "That was it." "That is a state where it gives out white heat."
The miserable Kansan had not thought to take it, being busy with the Beacon Building or the water hazard at the Emporia Country Club, and then, as the Col-o-nel took her arm she lifted the Eyes to the stupid clod of a Kansan and switched on all the joyous incandescence of her lamps as she said, addressing the Frenchman but gazing sweetly at the American, "Col-o-nel, will you please carry my books?"
Then the light dropped to the floor. I could see the outlines of his figure and a weird, single string of incandescence. Hobart turned and I leaped. It was a blur, the form of a man melting into nothing. I sprang into the room, tearing down the curtains. Hobart was on top of me. But we were too late. I could feel the vibrancy of something uncanny as I rushed across the space intervening.
He was convinced from the first that the true solution of the problem lay in a lamp which should have as its illuminating body a strip of material which would offer such a resistance to the flow of electric current that it could be raised to a high temperature incandescence and be of such small cross-section that it would radiate but little heat.
Each and all the lights must be produced and operated with sufficient economy to compete on a commercial basis with gas. The lamp must be durable, capable of being easily and safely handled by the public, and one that would remain capable of burning at full incandescence and candle-power a great length of time.
"I do not think my father would let me," she answered, with her eyes cast down upon her lace-frame. Barebone leant forward to put together the logs, which burnt with a white incandescence that told of a frosty night. The Marquis had business in the town, and would soon return from the notary's, in time to dress for dinner.
It may be presumed that in reality the gaseous substances, which, by their sudden incandescence, had produced the apparent conflagration, lay comparatively near the surface of the star, while the screen of cooler materials intercepting large portions of its light was situated at a considerable elevation in its atmosphere. The object, meanwhile, steadily faded.
Near the fires for the cooking, the melting of water and the forge, that were kept glowing all night, the tools were stacked, to help preserve their temper. The aurora quivered in varying incandescence as Rainey watched Lund prodding at the floe ice with a steel bar.
This nose vigorously divided a pale face into two sections which seemed to have no knowledge of each other, for one side would redden under the process of digestion, while the other continued white. This fact is worthy of remark at a period when physiology is so busy with the human heart. The incandescence, so to call it, was on the left side.
