Across
  1. 3. a collection of real components, power sources, and signal sources, all connected so current can flow in a complete circle.
  2. 4. unit structure used to generate an electrical current by some means other than the motion of a conductor in a magnetic field.
  3. 5. circuit when a path of low resistance is connected (usually by mistake) to a component.
  4. 7. wire non-conductive material resistant to an electric current.
Down
  1. 1. circuit path for transmitting electric current.
  2. 2. limits or regulates the flow of electrical current in an electronic circuit.
  3. 3. circuit a circuit is closed if the circle is complete, if all currents have a path back to where they came from.
  4. 6. circuit is open if the circle is not complete, if there is a gap or opening in the path.
