Tesla Currents

TESLA CURRENTS (Tesla), rapidly alternating electrical currents of high voltage that apparently have no physiological effect on the human and animal organism. Tesla currents are obtained as follows: in a circuit consisting of several turns of thick wire, a spark discharge gap (with a spark gap), and thick copper wires connecting all these parts of the circuit, oscillations are excited with the help of an induction coil and a capacitor (Leyden jar). Inside the turns of thick wire is placed a coil with a large number of turns of thin insulated wire wound in a single layer. Under the influence of oscillations in the primary circuit, oscillations are induced in this coil; their frequency is several million times per second; since the number of turns in the secondary coil is many times greater than in the primary, a very high potential difference can be obtained at the ends of the secondary coil. If, in addition, resonance in both circuits is achieved by special selection of capacitances and self-inductances, the oscillations in the secondary coil can acquire exceptional strength. A large number of very effective experiments are performed with Tesla currents: a Geissler tube, when brought to one end of the Tesla coil apparatus, begins to glow even before making contact with the corresponding terminal. When a hand is brought near one end of the Tesla coil, faint long blue sparks jump between them, causing no pain to the person. Despite the fact that during this process a discharge passes through the human body at voltages of hundreds of thousands of volts, and sometimes also with considerable current strength, no physiological effects on the organism are noted. The reason for this is partly that rapidly alternating currents have the property of spreading only over the surface of the conductor and not penetrating inside the conductor (the so-called "skin effect"). On the other hand, it is also essentially important that changes in ion concentrations, which cause physiological stimulation, do not have time to follow the extremely rapid oscillations. Tesla currents were first obtained by the Serbian physicist Nikola Tesla, who worked in the USA.
