Across
  1. 3. the primary and secondary are physically isolated (no electrical connection)
  2. 6. the ratio of the number of turns in the primary coil to the number of turns in the secondary coil
  3. 8. It is an electrical wire wrapped around the core on the output side
  4. 9. A ferromagnetic material that can conduct a magnetic field through it.
  5. 10. are electrical devices used to convert or "transform" AC voltage from one level to another. (high to low or low to high)
Down
  1. 1. An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
  2. 2. says that when two electrical coils are placed near to each other, AC electrical current flowing in one coil induces an AC voltage in the other coil.
  3. 4. It is an electricalwire wrapped around the core on the input side
  4. 5. used to reduce voltage from the main power line to a lower voltage that operates a machine’s electrical control system.
  5. 7. uses only one coil for the primary and secondary.
