How is it possible to have high voltage and low current? It seems
The power line has fairly low resistivity, so the total resistance is low, and so low voltage drop and low resistance yield low current, in accordance to Ohm''s law. In this way, it''s totally fine to have high voltage values and low current in power lines. Of these three explanations, I''m inclined to believe the third one.
