Why don't we just transform our voltage into above 9000 volts forever?
>infinite power.

>>	Anonymous Wed Apr 25 08:29:43 2012 No.4614629 >>4614606 What? If you connect a resistor to that 9000V line, it will always have a current running through it described by V=RI.

>>	Anonymous Wed Apr 25 08:33:07 2012 No.4614637 >>4614629 You got confused. Transformers are used to lower or rise voltage.

>>	Anonymous Wed Apr 25 08:35:24 2012 No.4614645 >>4614629 When did I even mention a transfo? If you connect a resistor to a 9000V line, it will always have a current described by V=RI. No exception. Whether the 9000V was achieved by a transfo or not has no importance.

>>	Anonymous Wed Apr 25 08:37:31 2012 No.4614647 >>4614641 The current in the primary will increase. That is all.

>>	Anonymous Wed Apr 25 08:40:56 2012 No.4614649 >>4614606 Ofc high voltage is lower current at same power. But why is it relevant the the current would be complete shit. I give a total of 0 shits about current.

>>	op Wed Apr 25 08:45:35 2012 No.4614658 >>4614647 Ok, thanks. so to get 9000V 3000W 0,3A on the secondary side we need 230V 3000V and somewhere around 11A? Wouldn't that still work as long as you use below 10000W?
