5. The Eastern Interconnect grid of North America transmits power at 230 kV. What would be the transformer turn (winding) ratio to step this voltage down to the 115 V used by residences (assuming there are no intermediary substations)? Is the number of turns in the secondary greater than or less than the number in the primary?
