What must happen to the electric current in power lines before it can safely enter your home

Answer

step down

Explanation

High voltages are very risky when using them. They can destroy electric devises if not controlled. High voltages are only required in factoring and industries.

The voltages in the power lines are very high. For safety purposes, this voltages are stepped down before they are distributed to the end users.

This reduces the risks when the consumers are using electricity.

We use the step down transformers to reduce these voltages in the power lines before they are supplied to the users.
