Answer :
Final answer:
Transformers are essential in reducing high voltages for electricity distribution and usage, ensuring safety and efficiency.
Explanation:
Transformers are used to lower the voltage for distribution and usage after high-voltage transmission. These devices play a crucial role in converting the electricity to safer levels for residential and commercial applications.
Example:
- Electric power is transmitted over long distances at high voltage to minimize current and reduce Joule losses due to resistive heating.
