I want to build a transformer for school project ...Suggestions ?
Okay so Here's what I've decided to do ..
(After rejecting several topics like tesla coil, van de graff generator, electroscope,galvanometer, DC-AC converter...I've arrived at this..)
I got 4 days to build it ...
So Im going to take some magnet wire ...say 240 turns..
thats the secondary ...Stuff the cardboard roll (like the one that comes with aluminium foil)with iron nails (to get a partial iron core)...wind the secondary on top of it..
Then wind the primary say 20 turns...
(now the ratio is 12 ...considering pathetic efficiency lets assume it to be 10)
So now I got a potential difference of say 50 volts in the primary ..
what I'll get a in secandory is 500 volt..
I can stick in a multimeter..to confirm the voltages...stick in a diode in the secondary ..and charge a capacitor ( layden jar, also homemade)...then discharge it to observe a awesome lethal spark...
[to the smart people : I know the dangers of high voltage, I will handle it carefully]
Pls understand , I have to create the entire thing myself,and demonstrate it with it's uses..
and also make a report file on it ..
Any suggestions ? pls tell
Any problems with my plan that you spotted ? pls share.
