  1. 10 -1 m/s

    Every conductor contains randomly moving free electrons in it. Movement of electrons in one direction caused by the Drift velocity generates a current. The drift velocity of an electron is very small usually in terms of 10 -1 m/s.

    Why do electrons need steady average drift velocity?
    We need to consider the average velocity of electrons because the velocity of an electron is not the same at every point in a conductor. Again, the velocities of all the electrons are not equal at any time or any point in the conductor. Let electrons are moving through a current-carrying wire of current I.

    How do you calculate drift velocity?

    How do you calculate drift?

    • Find the distance to your destination in nautical miles.
    • Divide this distance by your average speed in knots.
    • Multiply this time by the average speed (drift) of the current.
    • From your destination, plot the set of the current.

    Why is the drift velocity of electrons so low?
    Why is electron drift velocity low? Drift velocity is quite small, since there are so many free charges. If we have an estimate of the density of free electrons in a conductor, we can calculate the drift velocity for a given current. The larger the density, the lower the velocity required for a given current.

      • https://en.wikipedia.org/wiki/Drift_velocity

        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. Applying an electric field adds to this random motion a small net flow in one direction; this is the drift.
        Drift velocity is proportional to current. In a resistive material, it is also proportional to the magnitu…
