Why is electrical power transmitted at high voltage and low current? Answer : Power loss in transmission lines is given by: $$ P_{\text{loss}} = I^2 R $$ where $I$ is the current and $R$ is the line resistance. * If power is transmitted at **low voltage**, ... kV) using **step-up transformers** for transmission, and then step it down near consumers for safe distribution. ...
