Question

Define the following

¤ relaxation time

¤ drift velocity

¤ mobility

Answer 1

Heya user.......

_____________________________________________________________

QUESTION:- define the following

1). Relaxation time

2). Drift velocity

3). Mobility


ANSWERS:-

1). RELAXATION TIME

THE AVERAGE TIME INTERVAL BETWEEN SUCCESSIVE COLLISIONS OF ELECTRON WITH THE ATOM OR POSITIVE ION IN THE CONDUCTOR


2). DRIFT VELOCITY


DRIFT VELOCITY IS DEFINED AS THE AVERAGE VELOCITY WITH WHICH FREE ELECTRONS ARE DRIFTED UNDER THE INFLUENCE OF AN ELECTRIC FIELD

3). MOBILITY


MOBILITY OF A CHARGE CARRIER IS DEFINED AS THE MAGNITUDE OF THE DRIFT VELOCITY PER UNIT ELECTRIC FIELD

Hope it help

Answer 2

Hey dear !!


Here is yr answer///----



<> Relaxation time :


=> The time interval between the successive collosions of electfons !!



<> Drift velocity :


=> Average velocity of an electron, which attains in a material ... due electrical field or electric field.



<> Mobility :


=> Movement is known as mobility!




Hope it hlpz....
