Default +12V (10A) and -12V (0.3A) rating supply question

Hi,
a beginner question - can somebody please explain what would be the max current I can draw from a PSU that has one line with 12V (10A) and another line with -12V (0.3A) if I connect these 2 lines to a load? Would I be able to get 10A or will I get only 0.3A ?

Thank you
Arvind

Thanks DUG , wahab.

So is it possible to convert 12V(10A) to say 24V (2A) using some simple circuit? Any help appreciated.

Thanks

Convert - yes. Simple - no. Google DC-DC converter. It will normally involve big capacitors or inductors, and semiconductor switches.
