Hall probe calibration ? select the interpretation of a larger Hall voltage. Use this to support: Explain why synchronisation is needed.
- A.Hall probe calibration: larger Hall voltage indicates a larger magnetic flux density for the same probe current for Time-division multiplexing.
- B.Hall probe calibration: calls it a sound intensity reading.
- C.Hall probe calibration: uses resistance-temperature behaviour.
- D.Hall probe calibration: forgets the probe current condition.
Model answer
What a good answer should say
- The correct option is Hall probe calibration: larger Hall voltage indicates a larger magnetic flux density for the same probe current for Time-division multiplexing.
Explanation
Why this works
This is the best answer because the Hall probe calibration context requires that exact electronics relationship. The other options are incorrect because they use a different component, reverse the circuit behaviour, or omit the output interpretation required for Time-division multiplexing.
