    Hi everyone.

    I'm a 17 year old and I want to know all about the so called Tesla Coil.
    My scientific knowledge isn't quite large, but I quickly get the hang of things related to physics.

    So...

    What in fact is a Tesla Coil?
    Is it dangerous?
    And most importantly; can I build my own without spending a fortune?

    I already googled it, but there's so much about it that I can't really figure out what it's purpose, hazards etc are.

    Thanks in advance,

    Pharz

    If you don't know what Tesla Coil is, whay are you attempting to build one?

    I do know what it is, I just don't think I know enough about it to build one now.

    The only practical use I've ever seen one put to is as a lightning generator (to test lightning strikes on airplane components for example). That was a very, very large generator though. On a small scale, I haven't heard of them being dangerous, but I could be wrong.

    A tesla coil is basically a very powerful transformer, it can step voltages up to very high levels. Two tesla coils can be made to resonate with each other which can result in wireless energy transfer, that is, transfer of electricity with no interconnecting wires between two locations. I was going to build one a while back but decided against it due to the expense and time consumption.

    I am rather surprised at that. Tesla coils are generally ratht high frequency devices. The tests that I have done to simulate lightning used a very large capacitor bank, which was discharged in a BIG spark.

    High frequency current has very different characteristics with regard to penetration. Google "skin effect".

    Dang it. I'm confusing Tesla coils and Van de Graff generators.

    Van de Graff generators are not generally used to simulate lightning, but I have been involved in a test in which a huge Van de Graff was used to generate a pulse which created a threat-level large scale EMP pulse that simulates a nuclear high altitude EMP event.

    Well, since I can't remember or find where I saw that before, I'm probably wrong, so forget my previous comments.
