    it lowers the voltage in homes

    Explanation:

    this is due to safety reasons as a human cant survive power line voltages which are between 150k and 760k and if you plugged anything short of a piece of 1 inch thick wire not counting insulation it would immediately start smoking and burn the cable.

    Sample Response: High-voltage current enters the primary winding, which induces a magnetic field in the core. The magnetic field induces a current in the secondary winding. The voltage in the secondary winding is lower because it has fewer coils than the primary winding.
