Tesla is English Tesla direct transliteration, it is the magnetic induction unit in electromagnetics, especially in memory in the field of electromagnetics in the AC side of human made important contributions to the American inventor named Nicola Tesla. His life's major scientific achievement was that he invented the alternator, the high frequency generator and the high frequency transformer, as well as the famous artificial lightning "Tesla coils" mentioned in the program ".
Tesla coil is actually a pressurized device, this device invented by Tesla in 1891. Is composed of a primary coil, an induction coil, and a transformer, ignition, two capacitors. Using this device, you can generate a high frequency of high voltage current, but because the current value is very small, so the human body generally does not produce any harm.

Tesla coil from an electrical point of view is a resonant transformer, the use of it can be obtained on the high frequency of one million volts. There is a Tesla coil transformer, which can make the ordinary voltage increase, when Tesla primary circuit capacitor to discharge threshold, will produce the spark gap, and then through the spark gap discharge and conduction, so as to establish a primary resonant circuit. The top cover of the secondary coil and the earth can also be equivalent to a capacitor, so there will be oscillations. When the two coil oscillation occurs with equal frequency, resonance, primary energy will be poured into the secondary coil, the voltage of the discharge end is gradually increased, and the ionized air nearby, so as to discharge between top and near ground objects will release an arc, which is artificial lightning.
