b) transformers increase voltage before transmitting electrical energy economically over long distances through wires.
c) transformers decrease voltage before transmitting electrical energy economically over long distances through wires.
d) transformers convert nuclear energy to electrical energy before transmitting electrical energy economically over long distances through wires.
