Question

What is the conductivity when the Hall Effect coefficient is 5 and mobility is 5cm^2 /s.

(a) 100 S/m

(b) 10 S/m

(c) 0.0001S/m

(d) 0.01 S/m

I had been asked this question in a job interview.

I need to ask this question from The Hall Effect in division Conduction in Semiconductors of Electronic Devices & Circuits

Answer 1

Right choice is (c) 0.0001S/m

To explain: µ=σR

σ =µ/R

=5*10^-4/5

=0.0001 S/m.
