Question

2.When current flows along the length of the semiconductor slab and magnetic field applied is perpendicular the length to Hall voltage developed is

2 points

a)Along the length

b)Along the thickness

c)Along the width

d)Along the edges from where current enters​

Answer 1

${ \huge{ \sf{h{ \color{pink}e{ \color{pink}y{ \color{pink}y{ \color{pink}y{ \color{pink}y}}}}}}}}$

A) ALONG THE LENGTH

In Hall Effect, the electric field is perpendicular to both current and magnetic field so that the force due to magnetic field can be balanced by the electric field or vice versa.
