Question

Define the term drift velocity of charge carriers and show that the current density J

is related to the applied electric field E by the relation J= σE.

Where σ is conductivity.​

Answer 1

Answer:

he drift velocity is defined as the average velocity with which free electrons in a conductor get drifted under the influence of an external electric field applied across the conductor.

Explanation:

Answer 2

• 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.
