For long-distance transmission of power, in order to reduce losses in the wires by driving a low current at high voltage, we should

a) use a step-up transformer

b) change the length of the wires between transmission towers

c) not use a transformer at all

d) change the type of conducting material

e) use a step down transformer

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.)
