B)low so that overheating of the wires is minimized.
C)either of these
D)neither of these

Quizplus · Accepted Answer

Transmitting power at high voltages reduces the current for a given power level, which in turn minimizes the heating and energy loss in the transmission lines. This is due to the fact that power loss in wires is proportional to the square of the current (P = I^2R).
