Across
  1. 5. an electrical machine that converts electrical energy into mechanical energy
  2. 7. one in which all circuit elements are arranged in a single path
  3. 8. a vector field that associates to each point in space the force per unit of charge exerted on an infinitesimal test charge at rest at that point
  4. 10. the difference in electric potential between two points
  5. 11. the materials or substances which allow electricity to flow through them
  6. 12. a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage
  7. 16. basic property of matter carried by some elementary particles that governs how the particles are affected by an electric or magnetic field

Down
  1. 1. A machine that converts mechanical energy into electricity to serve as a power source for other machines
  2. 2. the physical interaction among electric charges, magnetic moments, and electromagnetic fields
  3. 3. the movement of electrons through a wire
  4. 4. a coil of wire usually in cylindrical form that when carrying a current acts like a magnet
  5. 6. device consisting of a core of magnetic material surrounded by a coil through which an electric current is passed to magnetize the core
  6. 9. a measure of the opposition to current flow in an electrical circuit
  7. 13. the region around a magnetic material or a moving electric charge within which the force of magnetism acts
  8. 14. is the force exerted by magnets when they attract or repel each other
  9. 15. an arrangement of electrical devices in a circuit in which the same potential difference is applied to two or more resistances with each resistance being on a different branch of the circuit
