Try reading it AGAIN !!!

IF you double the voltage into double the load, the CURRENT stays the same.

But double the voltage at the same current is TWICE the power.

Power = V x I "

Fine, but I don't know why you expressed it that way.

Looks like you NEVER read it.


There is still a limit to how much voltage you can have.
