Across
- 4. limits the current flowing in a circuit
- 7. only lets the current flow in the direction of the arrow
- 8. measures the current flowing in a circuit
- 9. measured in Ohm’s
- 12. closed circuit in which the current follows one path
- 13. a resistor that can be varied
- 14. measures the energy change in a circuit component
- 17. an energy user
- 18. commonly called a battery
- 19. a pathway along which an electric current exists and able to flow
Down
- 1. two or more cells connected in series
- 2. has a knob to vary the resistance
- 3. a thin wire which melts and breaks the circuit if the current gets too high
- 5. materials allow for charge transfer through the free movement of electrons
- 6. the circuit is divided into two or more paths
- 10. materials that impede the free flow of electrons
- 11. flow of electrons in one direction
- 15. Law V=IR
- 16. flow from negative to positive in wire
