Q1: Measurement of Hall coefficient enables the determination of

A recovery time of stored carrier

B type of conductivity and concentration of charge carriers

C temperature coefficient and thermal conductivity

D Fermi level and forbidden energy gap

ANS:B - type of conductivity and concentration of charge carriers

If a potential difference is developed across a current carrying metal strip when the strip is placed in transverse magnetic field. Hall effect is very weak in metals, but it is large semiconductors.
