Under the sub-caption of Self-induction and Inductance in the beginning of this chapter it was shown that it was the inductance of a coil that makes a current flowing through it produce a strong magnetic field, and here, as one of the constants of an oscillation circuit, it makes a high-frequency current act as though it possessed inertia.
The finished lamp is then photometrically tested, and placed on a support something like the Edison mounting. Upon it are engraved the working constants. As an ordinary practical result, these lamps, working with 50 volts and 1.15 amperes, give a luminous intensity of 20 candles, or the equivalent in luminous spherical intensity of 1.1 Edison A lamps.
If we decide upon such qualities as imagination, initiative, aspiration, appreciation, courage, loyalty, reverence, a sense of responsibility, integrity, and serenity, we have discovered some of the constants toward which all the work of the twelve years must be directed.
This characteristic of modern experiments that they consist principally of measurements, is so prominent, that the opinion seems to have got abroad, that in a few years all the great physical constants will have been approximately estimated, and that the only occupation which will then be left to men of science will be to carry on these measurements to another place of decimals.
The ideal language would resemble algebra, in which symbols, each representing a given numerical value, are connected by the smallest possible number of symbols of operation, +, , =, and so forth. To set two such statements side by side, or to modify them by inserting different constants, is then a comparatively easy process, capable of being regulated by simple general rules.
Such constants are the ordained changes in the rising and setting of sun, moon and stars; their obscurations by interpositions called eclipses; the heat and light from them; the seasons of the year, called spring, summer, autumn and winter; the times of the day, morning, noon, evening and night; also atmospheres, waters and lands, viewed in themselves; the vegetative force in the plant kingdom, that and the reproductive in the animal kingdom; likewise what is constantly produced when these forces are set in action in accord with the laws of order.
Actually, each ship of the Mekinese fleet was in overdrive, which meant that each had stressed the space immediately around it so that it was like a cocoon of other-space; as if it were out of this cosmos altogether and in another. In sober fact, of course, nothing of the sort had happened. An overdrive field changed the physical constants of space.
Now, what can you say for your Lafayettes, your Benjamin Constants, and your Tirecuir de Corcelles who have killed him? This cannot be allowed to pass in this fashion." He approached Marius, who still lay livid and motionless, and to whom the physician had returned, and began once more to wring his hands.
This relation between these three constants is known as Ohm's Law and as they are very important you should memorize them. What the Watt and Kilowatt Are. Just as horsepower or H.P., is the unit of work that steam has done or can do, so the watt is the unit of work that an electric current has done or can do. To find the watts a current develops you need only to multiply the amperes by the volts.
