WhatsApp: +86 18221755073As electricity flows through the wires, some of it dissipates as heat through a process called resistance. The higher the voltage is on a transmission line, the less electricity it loses. (Most of the electric current flows close to the surface of the transmission line; using thicker wires would have minimal impact on transmission losses.)
