When building a Tesla coil, one transformer is required to complete it. If you want to build the power by adding up another transformer to the coil, I would advice you to go by the plan established before by Nikola Tesla that was brought down in generations. First, building a coil, is something you shouldn't do if your electrical experience or knowable is not advanced.
In the related links box below, I posted Building A 250,000 Volt Tesla Coil.
the tesla coil has more resistance because it was created by tesla
You can buy or build a tesla coil which would be an excellent demonstration you could instead do something less exciting and kind of lame like make an induction circuit with two coils of wire to show wireless energy transfer through magnetic induction. I highly recommend the tesla coil as teaches these days usually have pretty bad demos but a tesla coil would really *spark* interest in young minds.
The Tesla family lived in a three-room flat, in a new building, across the street from the recently-built Junior High school .That was in the 1860s. by that date Tesla was in Grade Two of the primary school.
AC current or DC current can be used in transformers. A transformer is made of two coils of wire, the input coil induces a current into the output coil. Transformers change the voltage either up (step up transformer) or down (step down transformer). The amount of change in voltage is dependent solely on the number of windings in both coils in the transformer. DC transformers work exactly the same way AC transformers do.
The AC - and it must be AC - in the primary coil generates an alternating magnetic field around the coil; this alternating magnetic field induces a current in the secondary.
He had great achievements but I will mention two. The alternating electriticy wich is the most electricity used today and the coil wich is the basis for all wirelles comuication today.
Step up transformers, and step down transformers
they are two transformers named mudflap & skids
The two general categories of transformer, based on their construction, are (a) mutual transformers and (b) autotransformers.Mutual transformers have two coils, or 'windings', termed the primary (input side) and the secondary (output side), which are electrically isolated from each other, being linked with a magnetic field.Autotransformers have a single, shared, winding and so, do not provide isolation between the primary and secondary sides.Mutual transformers can be further classified, according to their function: e.g. power transformers, distribution transformers, isolation transformers, instrument transformers, matching transformers, etc.
A Tesla coil. It is a type of resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high voltage, low current, high frequency alternating current electricity. Tesla coils produce higher current than the other source of high voltage discharges, electrostatic machines. Tesla experimented with a number of different configurations and they consist of two, or sometimes three, coupled resonant electric circuits. Tesla used these coils to conduct innovative experiments in electrical lighting, phosphorescence, x-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920s, and in pseudomedical equipment such as electrotherapy and violet ray devices. Today their main use is for entertainment and educational displays.
Neon tube transformers are sized by the length of the tube. These types of transformers operate at voltages from 5,000 to 20,000 volts. If the length of the two tube sections are within the range of the transformers then two tubes can be connected together.
