Joule Thief

[TheNOP]

If I fed 1000v into a coil with 1000 turns of thin wire as its primary
and, if the secondary had 14 turns, would I get 14v out?

yes.
less the inevitable lost and that lost depend mainly on your core and wire resistance.

If I wound the secondary with a much thicker wire, as well, would this allow the output to be higher in amperage?

no
well, not exactly.

the currents at the secondary is determine by the primary and the turn ratio.
less the inevitable lost, as you can guess it by now. 

your secondary need wire size that can handle the currents.
making it with bigger wire size then it take(require), is sayed to be a waist of copper by the industries.
meaning it does not have any significant effect.

for me, more can also do less, bigger wires have less resistance.
but remember, it does not have any significant effect, meaning the gain is almost none.

An interesting website: http://www.batteryuniversity.com/partone-15.htm talks about pulses prolonging battery life with certain types of batteries.

@all

I just came accross some interresting information which might us all in out JT endeavours.

@Jadaro2600,
Thankyou for your links to the Walton Crockcroft web sites. I will now go and take a look at them.

@ TheNOP
Thankyou also for your reply

I posted my original questions to see if there would be an answer forthcoming, and the answers have arrived.

Now I can "see" that torrids are not the only method one can use to make a hi voltage, but I also knew that the WC is used in some "bug zappers and in some negative iron air purefiers.
I came accross a web page which had a Microwave oven transformer modification, but this trannie can put out 2000 volts from 240v primary.

My main reason on posting, was, what would occur, if I fed the JT output back into a transformer, and get it to make an amp output.
I'm sorry if I was not too clear about this, but I somehow think I have my answer.

Now I am thinking we need to be switching amps into/through the Joule Thief to get a usable amperage output.

Thanks for the link!!!

@jeanna

Nice work! Its looking really good!
