Tesla Coil !

Tesla coil is an awesome invention of Nikola Tesla; this material is actually a transformer. Transformers are usually step-up or step-down types which increase or decrease the input current respectively. The Tesla Coil is an air-core transformer with high frequencies.









It is a step up transformer which increases the given 120 volts AC to nearly 100,000 volts. The discharge is usually in the form of electrical arc. These unbelievable coils have in the past were known to light up florescent lights which were almost 50 feet away, wirelessly.


The other fact is that there is a direct conversion of electricity to light which does not need the electrodes, unlike the normal lights. What it means is that, the florescent lights which have already burnt out can also produce light.
