Questions & Step-by-Step Solutions

What type of transformer is used for electrical isolation?
  • Step 1: Understand what a transformer is. A transformer is a device that changes the voltage of electricity.
  • Step 2: Learn about the purpose of an isolation transformer. It is used to separate two electrical circuits.
  • Step 3: Know that the primary winding is where the electricity comes in, and the secondary winding is where the electricity goes out.
  • Step 4: Realize that an isolation transformer prevents direct electrical connection between the primary and secondary windings.
  • Step 5: Conclude that an isolation transformer is specifically designed for electrical isolation.
