What happens to the Hall voltage if the current in the conductor is doubled while keeping the magnetic field constant?.
- A.The Hall voltage is halved.
- B.The Hall voltage remains the same.
- C.The Hall voltage is doubled.
- D.The Hall voltage is quadrupled.
Model answer
What a good answer should say
- The Hall voltage is doubled.
Explanation
Why this works
According to the Hall effect principle, the Hall voltage is directly proportional to the current flowing through the conductor. Therefore, if the current is doubled while the magnetic field remains constant, the Hall voltage will also double.
