Ответ:
It passes through a step-down transformer.
Explanation:
Electric current in power lines must be stepped down before they enter our homes because they carry a very high voltage.
The voltage can destroy appliances that have very low voltage.
In this regard, a step down transformer is used to achieve this effect. The transformer brings the voltage to a level fit to consumers to use. When voltage is stepped down, appliances can work perfectly.Ответ:
