Questions & Step-by-Step Solutions

What is the effect of increasing the load on a transformer?
  • Step 1: Understand what a transformer does. A transformer changes the voltage of electricity.
  • Step 2: Know what 'load' means. Load refers to the amount of electrical power being used by devices connected to the transformer.
  • Step 3: Realize that when you increase the load, more power is drawn from the transformer.
  • Step 4: Understand that as the load increases, the transformer has to work harder to supply the extra power.
  • Step 5: Recognize that this extra work can cause more energy losses in the form of heat.
  • Step 6: Conclude that these losses reduce the overall efficiency of the transformer.
