Across
  1. 6. An approximate value based on available data, a graph or a calculation.
  2. 8. A device used to measure electric current. It is connected in series in a circuit.
  3. 9. Another name for potential difference: the energy transferred per unit of charge between two points, measured in volts (V).
  4. 11. difference The energy transferred per unit of electric charge between two points in a circuit. It is also called voltage and is measured in volts (V).
  5. 12. A circuit arrangement in which components are connected along the same path. An ammeter is connected in series.
  6. 14. A complete, closed path through which electric current can flow.
  7. 16. Estimating a value beyond the range of the data that was collected. This is generally less reliable than interpolation.
  8. 20. A circuit arrangement in which components are connected on separate branches. A voltmeter is connected in parallel with the component being measured.
  9. 22. A device used to measure potential difference (voltage). It is connected in parallel across a component.
Down
  1. 1. A factor that is kept the same throughout an investigation to make the test fair.
  2. 2. The variable that is deliberately changed by the investigator.
  3. 3. Estimating a value that lies between measured data points and within the range of collected data.
  4. 4. Measurements or observations collected during an investigation.
  5. 5. The variable that is measured or observed in response to changes in the independent variable.
  6. 7. The unit used to measure potential difference or voltage.
  7. 10. A device that transfers electrical energy into movement (kinetic energy).
  8. 13. of best fit A straight or curved line drawn to show the overall pattern or trend in plotted data.
  9. 15. A factor in an investigation that can be changed, measured or controlled.
  10. 17. The general pattern or direction shown by a set of data, such as current increasing as voltage increases.
  11. 18. The rate at which electric charge flows through a circuit. Current is measured in amperes (A).
  12. 19. The unit used to measure electric current. It is often shortened to amp or represented by A.
  13. 21. An electrical component that transfers electrical energy into light and heat energy.
