Question

what is drift velocity ? Find its value for a conductor. Derive its relationship with electric Current​

Answer 1

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.

Formula

v_{d}=\frac{I}{n e A}

v_{d} = drift velocity

I = current flow

n = free electron density

e = charge of an electron

A = cross sectional area
