  1. A galvanometer uses the magnetic force on a loop of wire in a circuit to measure
    current
  2. A commutator is a device that reverses the flow of current through an
    armature
  3. What is a coil of wire with a current called
    solenoid
  4. A turbine
    turns the armature of a generator
  5. When a wire with a current is placed in a magnetic field
    electrical energy is transformed into mechanical energy
  6. Alternating current allows efficient electrical energy transmission because
    its voltage can be stepped up and stepped down
  7. What is a current that consists of charges that move back and forth in a circuit?
    alternating current
  8. The relationship between electricity and magnetism is called
    electromagnetism
  9. A generator uses motion in a magnetic field
    to produce an electric current
  10. Generating an electric current from the motion of a conductor through a magnetic field is called
    electromagnetic induction
  11. Most electric motors have an arrangement of hundreds of loops or wire wrapped around an iron core.  This arrangement is called
    armature
  12. An electric generator transforms what kind of energy into electrical energy?
    mechanical energy
  13. A solenoid with a ferromagnetic core is called
    energy
  14. What is a device that increases or decreases voltage.
    transformer
  15. Can a generator transform electrical energy to mechanical energy?
    False: an electric motor transforms electrical energy to mechanical energy?
  16. The type of current produced by the battery in a calculator is a direct current.
    true
  17. Is  mechanical energy?
    False, the energy associated with electric currents is called electrical energy
  18. In a transformer, the primary coil is connected to a voltage source.
    true
  19. An electric current will be induced in a conductor when the conductor when the conductor moves through a magnetic field.
    true
