Question

Calculate the Hall Effect coefficient when number of electrons in a semiconductor is 10^20.

(a) 0.625

(b) 0.0625

(c) 6.25

(d) 62.5

This question was addressed to me by my school teacher while I was bunking the class.

I'd like to ask this question from The Hall Effect in portion Conduction in Semiconductors of Electronic Devices & Circuits

Answer 1

Correct choice is (b) 0.0625

Explanation: R=1/ρ

=1/(1.6*10^-19*10^20)

=0.0625.
