55. At the power substation near the edge of a large city, voltages are reduced and current is
sent to the various neighbourhoods. Why don't the neighbourhoods get more current
than what came from the high voltage lines?

a. There are special transformers that reduce current and voltage at the same time.

b. A special DC system is used to change the voltages

C. The total current did increase, but it split off into various smaller currents.

d. The current is run out of energy at the substation so less is available to the
neighbourhoods.
