Answer:
See the explanation below
Step-by-step explanation:
By means of an electrostatic machine called Transformer, there are various types of transformers from those used for commercial and residential applications to those used at the industrial level. Its working principle is the same which is called induction. The current enters through an electric coil (copper spiral) called primary winding, this current generates a magnetic field, and if a second winding is placed inside the first, an electric current is generated in the second winding, that is called induction. If the second winding has half the turns of the first winding, The half of the original voltage will be obtained. This allows by means of different electrical transformers located in different places of the transmission of electrical energy, it can be reduced from a voltage of 700,000 volts to 120 volts
