Meters and troubleshootingQuestion 1190 of 1506

What makes the Hall-effect voltage rise in a power sensor?

  1. Higher temperature of the plate only
  2. A higher supply frequency only
  3. More current and a stronger field
  4. A heavier layer of insulation on it
Show answer

Correct answer: More current and a stronger field

The Hall voltage is proportional to the current times the magnetic field strength, which is a multiplication.
