The Tesla High Frequency Coil; Its Construction and Uses (Paperback)


This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ...great advantage lies in setting up the currents of enormous frequency. When any condenser is discharged, the discharge may take one of several forms, depending only on the three electrical constants, of the discharging circuit--inductance, capacity, and resistance. The discharge may be either oscillatory or entirely unidirectional, consisting only of a gradual equalization of the potentials on the two plates. This may be made clear by the following mechanical illustration. Suppose a glass U-tube to be partly filled with mercury, and the mercury to be displaced so that the level in one side of the tube is higher than in the other.. There is then a force due to the difference of level, tending to cause the liquid to return to an equal height in both limbs. If the mercury is now allowed to return, but is constrained, so that it is' released slowly, it goes back to its original position without oscillations. If, however, the constraint is suddenly removed, then owing to the inertia of the mercury it overshoots the position of equilibrium and oscillations are created. If the tube is rough in the interior, or the liquid viscous, these oscillations will quickly subside, being damped out by friction. What we cull inertia in material substances corresponds with the inductance of an electric circuit and the frictional resistance experienced by a liquid moving in the tube, with the electrical resistance of a circuit. If we supjwse the U-tube to include air above the mercury'and to be closed up at its ends, the compressibility of the enclosed air would correspond to the electrical capacity in a circuit. The necessary conditions for the creation of mechanical oscillations in a material system or substance are that there must be a self-recovering...
