Across
  1. 3. The movement of electrical energyFrom one part of the circuit to another when you plug in a fan electrical energy changes into motion and Sound Energy
  2. 6. The Continuous Flow of electric charges through a circuit it is like the River of electricity that keeps the device working
  3. 7. A complete Loop that lets electricity flow continuously when you turn on a lamp electricity moves in a closed circuit from the outlet to the light bulb
  4. 10. opposition that slows down electric current as it moves through a material for example a thin wire has more resistance than a thick wire and it can get hotter
  5. 11. The positive side of a battery where electrons flow in. The cathode is where electrical energy is received or used
  6. 12. Immaterial that resists the flow of electrical current plastic coatings on wires are insulators that protect us from Electric shocks
  7. 13. a closed path that allows electrical energy to move through it a flashlight works only when its circuit is complete from the battery to the bulb and back
Down
  1. 1. a circuit that has more than one path for the current to travel in a house lights are wired in parallel so one can turn off While others stay on
  2. 2. circuit in which electrical current flows through only one path if one bulb burns out in a series circuit all the others go out too like an old Christmas
  3. 4. a device that stores chemical energy and changes into electrical energy the positive and negative ends of a battery send electrons through a circuit to power a light or a motor
  4. 5. the negative side of a battery where electrons flow out in a battery powered toy the anode pushes electrons into the wires
  5. 7. A material such as copper wire that allows electrical current to pass easily conductors are used to connect all parts of a circuit
  6. 8. A circuit that has a break where electricity cannot float when you remove a battery or flip a light switch off the circuits is open and the current stops
  7. 9. The energy made by the movement of electrical charges called electrons we use electrical energy every day to power lights computers and refrigerators
