Question

The magnitude of drift velocity is of the order of: a) 0.1 m/s b) 0.01 m/s c) 0.001 m/s d) 0.0001 m/s​

Answer 1

Answer:

c) one is correct answer

Answer 2

The magnitude of drift velocity is of the order of: 0.0001 m/s ( Option d is the correct answer)

• A drift velocity in physics is the average speed attained by charged particles—like electrons—in a material as a result of an electric field.
• Typically, an electron in a conductor will move randomly at the Fermi velocity, resulting in an average velocity of zero. The drift is the little net flow that is added to this random motion when an electric field is introduced.
• Drift velocity and current are directly correlated. In a resistive material, it is also proportional to how strong the external electric field is.
• Therefore, drift velocity can be utilised to explain Ohm's law. The simplest form of the law is: u= µE
• where the electron mobility of the substance,, and the electric field are all present, and u is the drift velocity. These quantities have the following units in the MKS system: m/s, m2/(Vs), and V/m.

Hence, The magnitude of drift velocity is of the order of: 0.0001 m/s.
