Question
Define the drift velocity of electrons in a conductor?
Open in App
Solution
It is defined as an average velocity attained by the charged particles (electrons) in a material due to an electric field.
The drift velocity can be calculated by using the following formula:
I
=
nAvQ
where,
v
=
drift velocity of electrons
n
=
number of electrons
A
=
area of cross-section of a conductor
Q
=
charge of an electron
I
=
current flowing through the conductor.
