Questions & Step-by-Step Solutions

What is the main disadvantage of using a step-down transformer?
  • Step 1: Understand what a step-down transformer does. It reduces voltage from a higher level to a lower level.
  • Step 2: Know that when voltage is reduced, the current increases in the secondary winding (the part that delivers power).
  • Step 3: Realize that higher current can lead to more energy losses in the form of heat due to resistance in the wires.
  • Step 4: Conclude that the main disadvantage of using a step-down transformer is that it can have higher losses because of this increased current.
