Due to the sometimes vast lengths of wire required to transmit the electrical energy from the utility-owned generating plants normally located on lakes or rivers, to the cities and the industrial, commercial, or residential sites that represent the connected loads, 3-phase __________ are used to step up the circuit voltage and step down the circuit current to overcome or decrease the energy losses of the cumulative wire resistance presented to the electrical circuit.
At the load end of the utility-owned transmission/distribution system, more 3-phase or single-phase AC __________ are used to step the current down and step the load voltage up.
A) alternators; alternators
B) generators; generators
C) transformers; transformers
D) motors; motors
