A small current of high-voltage electrons can carry the same amount of power as a large current of low-voltage electrons. Cross-country power transmission systems operate with a small current of very high-voltage electrons because this arrangement
A)	minimizes the fraction of total electrical power wasted as heat in the transmission wires.
B)	eliminates the need for transformers at either end of the cross-country transmission system.
C)	makes it possible to deliver electrical energy to the consumer continuously without requiring a complete electrical circuit. Only a single wire is needed to carry the power.
D)	is less likely to give anyone a shock than a system in which a large current of low-voltage electrons carries the power.
