Answer

See explanation.

Work Step by Step

Equation 27.30 relates the concentration of mobile charge carriers to the electrostatic field in the material. All else being equal, a poor conductor has a lower concentration of mobile charge carriers than a good conductor does, which corresponds to a strong electrostatic field. A strong electrostatic field results in a high Hall-effect voltage.
