  • Why is electricity transmitted at high voltages? - Solved

    These high voltage lines transmit electric power generated at power stations which are situated at remote locations. Power stations are built away We can improve the efficiency of power transmission by reducing the power losses and cost of conductor and equipment required for power transmission.
