For long-distance transmission of power, in order to reduce losses in the wires by driving a low current at high voltage, we should use a step-up transformer (a) .

(That's at the beginning, to step-up the voltage for long-distance transmission. And then use a step-down transformer at the end, to reduce the voltage just before we pour it into the customer's house.)
