I am reading about Transformers and have a question about the specifics of reducing loss in a transmission line.
The book says because engineers cant do much about the wire resistance or the power consumed by the loads they can adjust the voltage and thereby the current using P=EI. If the voltage was increased by a factor of 10 then the current could be reduced by a factor of 10 resulting in reduced loss.
How is it possible to have for example
100W = 10 V * 10 A
and
100W = 100V * 1 A
If the resistance is the same in both? Doesn't that violate Ohms Law?
