I would be grateful if anyone could clear up my confusion with this relatively simple concept. It has been bugging me for 3 years now and I've never had a clear answer from my teachers.
Consider a power line transmitting electricity:
Power loss in the wire = I2R = VI
To reduce power loss I am told you are to reduce the current...
However when you reduce the current (say 10x) you must increase the voltage 10x.
I = V/R therefore Power can also be written as V2/R
If you are increasing the voltage Power loss is anything but decreased?
