I have a lead battery charger whose output 24V @1.3A . To make the 24V into 12 V I just add two resistors in parallel ,rite?
Will that have any affect on the 1.3A? What values should the resistors be?

I rest my case!

uchhh, just answer it!
if you wont answer ill just see what happens when i try to do it myself.
great soeren you really helped a lot.

oops i feel kind of stupid now...

I typed parallel instead of in series. :-[ ::) :-[

Well, this was just ment as a comment to my advice about grabbing some books on the basics.
But your answer is "allright, then I'll go harm myself and blame you for not telling me how wrong I was"
Tsk tsk...
Follow my advice!
You can NOT get a complete education by asking questions in a public forum. Go read some books and follow some experiments in those books, then you'll learn, gradually, in a pace that makes it possible to get it to stick.
This question shows a total lack of understanding of Ohms Law and that is a non-escapeable need-to-know, so READ some BOOKS before you hurt yourself and tires everybody out.

OK

So the equation you want to use is ohm's law:
voltage = current * resistance
So the method you want to do is HIGHLY inefficient, but would work . . .
You probably would want to use a transformer . . .
Why do you have 24 volts? Might be easiest to buy a 12V battery charger.
