Transformers

• transformers

  consists of a primary and secondary coil wound on an iron core
• types of transformers

  • step up
  • step down
• Vp / Vs = Np / Ns
• Vs x Is = Vp x Ip
• step up transformers

  • increase the potential difference
  • more turns on the secondary coil
• step down transformers

  • decrease the potential difference
  • more turns on the primary coil
• types of transformers

  A) step down

  B) step up
