Question
Hall effect device can be used to-
The correct answer is
Multiply two signals
R_H is the Hall coefficient, a property of the material. Based on the fundamental operating principle and the Hall voltage formula, the most direct and common application of a Hall effect device among the choices is the multiplication of two signals. Therefore, the correct answer is Multiply two signals.
