Question

Formula of drift velocity

Answer 1

Answer:

The formula for evaluating the drift velocity of charge carriers in a material of constant cross-sectional area is given by: where u is the drift velocity of electrons, j is the current density flowing through the material, n is the charge-carrier number density, and q is the charge on the charge-carrier.

u= \mu E

Answer 2

Answer:

i=vAnq

Explanation:

i- current

v- drift velocity

A-area of cross section of conductor

n- charge density

q-charge on each carrier
