# Hall coefficient

## Definitions

### Electronics

- A constant of proportionality utilized when performing calculations associated with the Hall effect. When calculating the strength of the electric field,
, the following formula may be utilized:*E*_{H}=*E*_{H}, where*R*_{H}JBis the Hall coefficient,*R*_{H}is the current density, and*J*is the magnetic flux density. The*B*__sign__of the Hall coefficient changes with the sign of the__charge carrier__, so it serves to indicate the sign of the majority carrier. Also called Hall constant. - synonymHall constant
