Questions & Step-by-Step Solutions

What is the primary purpose of a transformer in a power generation system?
  • Step 1: Understand that electricity is generated at a certain voltage level.
  • Step 2: Know that high voltage is needed for long-distance transmission to reduce energy loss.
  • Step 3: Learn that a transformer can increase (step up) the voltage for efficient transmission.
  • Step 4: Recognize that when electricity reaches its destination, it needs to be at a lower voltage for safe use.
  • Step 5: Understand that the transformer can also decrease (step down) the voltage for distribution to homes and businesses.
