Across
  1. 2. it lets eletricity flow through it easily
  2. 3. electrons flow past a point in a complete electrical circuit
  3. 4. diagram it represents the circut and the shapes and lines that make it a circut
  4. 6. Materials that do not allow electricity to pass
  5. 9. electrical path that branches so that the current divides and only part of it flows through
  6. 10. a divice that converts chemical energy and converts it to eletricity
  7. 11. unit of measurement for electromotive force, expressing the electric tension or the difference in charge between two points
  8. 14. allows heat and electricity to pass through it
  9. 15. pressure from an electrical circuit's power source that pushes charged electrons
  10. 18. service that delivers usable electrical circuit over-current safety
  11. 19. a path eletricity flows in
Down
  1. 1. flow of eletrical power of charge
  2. 4. powers eletrical circuts
  3. 5. the resistance of a wire of that substance with unit length and unit area
  4. 7. which all circuit elements are arranged in a single path
  5. 8. electrical current in a circuit can be calculated by dividing the voltage by the resistance
  6. 12. an electrical component that can disconnect or connect the conducting path in an electrical circuit
  7. 13. measure of the opposition to current flow in an electrical circuit
  8. 16. Resistance is measured in BLANK, symbolized by the letter “R”
  9. 17. a unit of measure for electric current
