A transformer circuit, created during 1981 by a man named Nikola Tesla, utilized to produce a reasonably high current with a high voltage. The circuit said to produce a high frequency of electricity with alternating currents. Tesla had experimented with a variety of configurations, which consisted of two to three electric circuits that are resonant. He made use of these to perform advanced experiments in the field of x – ray generation, electrotherapy, electrical lighting, alternating current in high frequency and transmit electrical energy even without the use of any wires. They called it the Tesla coil. These are unique in the fact that they are able to create very powerful fields.
The Tesla Coil Design
Its early design makes use of a medium voltage to a high voltage source of power, high voltage capacitors and spark gaps, which are use to “excite” primary inductors with multiple layers as it produces high frequency currents of periodic bursts. These primary inductors are excited with the use of resonant and inductive coupling wherein both primary and the secondary circuits both be tuned so that they would echo or resonate within same frequency, which is typically between 2 MHz and 25 kHz with the use of the Tesla coil. The modern coil designs based on this idea and could be seen during science fairs or museums.
The Tesla Coil Early Uses
Until 1920s, these coil circuits were practically used for the purpose of wireless telegraphy in spark gap transmitters in the radio. They were use in pseudomedical devices and in electrotherapy. An example for this device named as “violet” ray though the Tesla coil circuits are neither the first nor the single ones that used as spark transmitters. They were others that enthusiasts used and they only made use of these coil types just to try it out. Its transformers operate with a substantially distinct manner than any conventional transformer that we know of today.
Now these are used for educational displays and for entertainment! Many groups like research institutions, independent experimenters, science museums and many high voltage enthusiasts create their own coils. Although there were, still many electronic circuit controllers that have been developed in the new generation, the Tesla coil has already proven itself extremely reliable and its unique spark gap pattern is cheaper as compared to the others. These designs have already graced many science venues and there are trusted websites that teaches you how to make tesla coil at your very home.
