These produce a limited current at rather high voltage (about 20 kV; generally about 20 mA). They are short-circuit protected, but be aware that they can be LETHAL. The output is simply a voltage-stepped- up version of the input, so the frequency is still 60 Hz (though probably with quite a bit of harmonic distortion). Since they don't produce RF, there are a lot of experiments that you can't use them for that the tesla coil might be good for. (If you change the frequency used to excite a neon light bulb, for example, the color goes from the usual orange to a pretty purple as you get up into the 10's of MHz...) > >Hope this is of interest. >----------
