Main Question or Discussion Point
As a general rule, if a company was to transmit a certain amount of electrical power than transmit at the highest voltage hence lowest current with P=IV. This is done in order to reduce waste power given by PowerWaste=I^2R. However voltage and current are proportional and related by V=IR. Therefore at a certain power transmission, if one was to maximise V and minimise I than the transmission line must have a very high resistance (although given from the PowerWaste equation high I is much worse than high R). Is my conclusion correct?
