hi,
i probably don't need to give you all this information, but i will anyway :)
i have a flyback transformer from a TV connected to a 30V 1A power supply via a transistor from a TV (a high power line output transistor), and the signal on the base of the transistor is around 100KHZ alternating dc sine-wave at around 5-10V, the flyback transformer produces a spark at a maximum length of around 2.5 cm, which i assume is a maximum of 20KV, and i always assumed that if i touched it i would get a nasty shock (though i have never got a shock from it, it would atleast burn me as i can light toilet paper with it), but it would be harmless, but today i calculated that as the current drawn from the power supply is around a third of an amp, the maximum current from the flyback transformer's high voltage (around 20KV) output (not accounting for any losses) would be .49MA, the transistor gets very hot within a few seconds of operation, and has to be immersed in water to keep it cool (atleast that's the easiest way to do it), could this current and voltage combination be fatal? could you please give me a rough way to calculate the LD 50 of some current and voltage combinations?
thank-you for enlightening me as there is little information on the WWW about it.
thanks in advance, alf.
