We then examined the connections and ran the trouble back to the coil. There was plenty of current and plenty of voltage, but only a little blue spark, which could be obtained equally well with the coil in or out of the circuit, and yet the coil did not show a short circuit, but before we finished our tests the spark suddenly appeared.
The easiest way to get a clear conception of how a wireless transmitter sends out electric waves and how a wireless receptor receives them is to take each one separately and follow: in the case of the transmitter, the transformation of the low voltage direct, or alternating current into high potential alternating currents; then find out how these charge the condenser, how this is discharged by the spark gap and sets up high-frequency currents in the oscillation circuits; then in the case of the receptor, to follow the high frequency currents that are set up in the aerial wire and learn how they are transformed into oscillations of lower potential when they have a larger current strength, how these are converted into intermittent direct currents by the detector and which then flow into and operate the telephone receiver.
Every such coming heightens the voltage of spiritual power in the world. The greatest stories of the world are the stories of such comings. Of first importance in the education of children is the institution of an ideal of the imminence of great helpers, the Compassionates. Children become starry-eyed as they listen.
That was a high-current, and low-voltage arc. Couldn't you tell by the sound that no great voltage as atomic voltages go was smashing across there? If we were getting atomic voltage and power there'd have been a different tone to it, high and shriller. "Now, did you take any readings?" "What do you think, man? I'm human.
Arcot spent the rest of the evening teaching them the Venerian system of telepathy. They all rose at nine. Arcot got up first, and the others found it expedient to follow his example shortly thereafter. He had brought a large Tesla coil into the bedroom from the lab and succeeded in inducing sufficient voltage in the bedsprings to make very effective, though harmless, sparks.
I can't help thinking, after reading the modern men, that they are like the transformers in an electric power-plant. The Latins are the generators of ideas, and these other chaps are transformers. They reduce the voltage, lose a lot in leakage, but are useful because they make the current available to the small man. It's a rather technical illustration, but that's what I mean.
I hear a good deal about the exertions to which your papers go to be on the street first with extras, but I'll bet there has never been more voltage in the competition here than there was in Homeburg the night old man Ayers and young Simpson arrived at the post-office door at precisely the same second and got their baskets and themselves in a hopeless jam.
Aylsworth said: "In like manner the iron element had to be developed and improved; and finally the iron, which had generally enjoyed superiority in capacity over its companion, the nickel element, had to go in training in order to retain its lead, which was imperative, in order to produce a uniform and constant voltage curve.
The word capacitance means the electrostatic capacity of a condenser or a circuit. The capacitance of a condenser or a circuit is the quantity of electricity which will raise its pressure, or potential, to a given amount. The capacitance of a condenser or a circuit depends on its size and form and the voltage of the current that is charging it.
All of these have become standard practice and are operated at the usual voltage of from 500 to 600 volts. The current on lines of any considerable length is alternating current, supplied from large central generating stations and transformed to direct as occasion may demand at suitable sub-stations.
