Question

Write a notes on driff velocity.​

Answer 1

$\huge{\underline{\mathbb{\red{ANSWER}}}}$

In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero.

Answer 2

Answer

Drift velocity is the average velocity of the electrons moving towards the positive terminal of the battery when a potential difference is applied across a conductor.

Formula To Calculate Drift Velocity

We can use the following formula in order to calculate drift velocity:

I=nAvQ

• I is the current flowing through the conductor which is measured in amperes.

• n is the number of electrons.

• A is the area of the cross-section of the conductor which is measured in m^2.

• v is the drift velocity of the electrons.

• Q is the charge of an electron which is measured in Coulombs.
