How do I change Low current DC to high current DC? Answered
Suppose I have a high voltage source of DC with fractional milliampere current. How can I increase the current?
I think Watts is fixed with respect to source. So, if there is 12000 Vdc at 1 milliampere (12 Watts??) I should, in theory, be able to get 12 Vdc @ 1 amp.
Practicality aside, is this correct?
Practicality engaged: Is 12 Vdc at 1 amp possible, and how? 4 amps???
