Questions & Step-by-Step Solutions

What is the main purpose of a transformer in power systems?
  • Step 1: Understand that electricity is generated at power plants.
  • Step 2: Know that electricity needs to travel long distances to reach homes and businesses.
  • Step 3: Realize that high voltage is better for long-distance travel because it reduces energy loss.
  • Step 4: Learn that transformers can increase (step up) the voltage for efficient travel.
  • Step 5: Understand that when electricity reaches its destination, transformers can decrease (step down) the voltage to safe levels for use.
  • Step 6: Conclude that the main purpose of a transformer is to adjust voltage levels for better electricity transmission and distribution.
