Across
  1. 1. Calculate the resistance when potential difference is 4.8V and current is 0.75A
  2. 3. The voltage supplied to homes
  3. 9. This component allows you to adjust the potential difference across the lamp
  4. 11. An electric circuit with only one path through which charge can flow
  5. 12. This is designed to melt and break the circuit if the current is greater than stated on it
  6. 13. Increasing the current makes the temperature increase and the resistance to increase
  7. 14. This component pushes the electrons around the circuit
  8. 15. Current repeatedly reverses its direction.
  9. 16. Type of current in a battery powered torch because it is in one direction only
  10. 17. This only allows current through in one direction only
Down
  1. 2. states a relationship between voltage, current, and resistance
  2. 4. This is placed in parallel to the component you are measuring
  3. 5. A temperature-dependent resistor
  4. 6. An electric circuit with two or more paths through which charge can flow
  5. 7. A nationwide network of cables and transformers
  6. 8. The opposition to the flow of electric charges in a material
  7. 10. This measures the current in the circuit
  8. 12. The number of cycles it passes through per second
