Drift velocity of electrons is ....... ....

Drift velocity of electrons is ....... .

A

same as velocity of light.

B

larger than the velocity of light

C

negligible compared to velocity of light

D

zero

Text Solution

Verified by Experts

The correct Answer is:
C
negligible compared to velocity of light
The effective displacement of dragged electron in the presence of external electric field. The velocity of electron corresponding to this displacement is called drift velocity. The value of it is negligible in comparison with velocity of light.
