Talk:School Science/How to make a transformer

Ok I know this isn't very good but it's difficult to explain without a diagram. I will try to add a diagram in the near future.Theresa knott

What are mes bulbs ??


 * Sorted out on the page Theresa knott

Also you should mention that your 4v power supply has to be AC. Daniel MacKay
 * Ok I've do it but you could have just done that for me. Do I have to do everything round here? ;-) Theresa knott


 * Yes. :-D Gorm

How about mentioning the actual result(brigter/darker on the secondary)? Gorm 09:41 13 Jul 2003 (UTC)
 * Thanks Tessa!

OK, that diagram sucks. It doesn't look anything like Optimus Prime. --Dante Alighieri 08:09 12 Jul 2003 (UTC)
 * True, but it does transform. Move the two bulbs down, the u shaped cores over them, as wheel arches and make a chassis with the rest of the lines and you've got a pretty damn good go-cart Theresa knott 04:39 15 Jul 2003 (UTC)

Wouldn't the bulb also dim when cores are set apart? Should this be mentioned? Nikola 19:38, 12 Nov 2003 (UTC)
 * Yes the bulb would dim, but setting them apart with an air gap would be very difficult to do in practice. You'd either get no light at all or if you move them closer together the magnetic attraction between the C cores forces them together. There's no way I can pull them apart. I suppose you could put something in the gap to keep them from slamming together I might give it a go and see what happens.Watch this space. theresa knott 14:26, 13 Nov 2003 (UTC)

I am somewhat concerned that the removal of the disclaimer may be problematic if someone tries these instructions (clumsily) and gets hurt. Waveguy 18:04, 4 Jan 2004 (UTC)

As maverick said, the disclaimer hasn't been removed, as it's already on the bottom of every page.It was a bit OTT in my opinion. I hate for it to put people off. This is a safe experiment. I have seen it done loads of times over the years by adults and 13-16 year olds and have never seen anything bad happen.The only way that I can think of in which someone might get seriously hurt is if they tried to plug it into the mains and got an electric shock. You'd have to be a real dimbo to do that, but just in case I've added instructions not to on the page. theresa knott 13:29, 5 Jan 2004 (UTC)

1.take two soft iron with u-shape 2.take a strip of coil and wrap around the  first iron 30 times. 3.again take a strip of coil wrap second iron for 60 or more times. 4.now join the 6v bulb in the second iron that is coil wraped for 60 times. 5.now give the ac curret through 30 times wrap iron
