Comparison microwave transformers, invisible copper wire
NOTICE: replicate this experiment can be very dangerous, only by people with knowledge of electricity.This video is a simulation of the transport of electricity from a primary power plant to a secondary power plant. In practice, a thin capillary wire inserted to the output of the primary transformer of 2000 volts communicates to the other secondary transformer, then it reverts the voltage to 2000 volts to 220 volts.
