Why an electron's drift velocity is so slow? - Physics Forums
2016年12月28日 · If you take the Drude-Sommerfeld model (i.e., the Drude model of the conduction electrons in a metal as an ideal gas together with Sommerfeld's use of the Fermi statistics) then of course the electron velocity consists of the collective flow ("macroscopic velocity" or "drift velocity") of the conduction electrons, making up the macroscopic ...
Why Does Electron Drift Speed Remain Constant Despite …
2013年8月19日 · The drift speed of an electron is affected by the strength of the electric field, the density of charge carriers, and the cross-sectional area of the conductor. It is also affected by the type of material the conductor is made of, as some materials allow for easier movement of electrons than others.
How Fast Do Electrons Drift in an Iron Wire? - Physics Forums
2009年3月17日 · The electron drift speed is typically measured using a device called a Hall probe, which is a small semiconductor material with a magnetic field applied to it. As the electrons move through the material, they experience a force due to the magnetic field, which can be used to calculate their drift speed.
Electron drift speed in a copper wire. - Physics Forums
2007年4月8日 · The electron drift speed in a copper wire is much slower than the speed of light. While the speed of light is approximately 3 x 10^8 meters per second, the average electron drift speed in a copper wire is on the order of millimeters per second.
Solve Electron Current in 1.00mm Gold Wire: How Long for 1 Mole?
2007年3月13日 · Homework Statement The electron drift speed in a 1.00 -mm-diameter gold wire is 5.50*10^-5 m/s How long does it take 1 mole of electrons to flow through a cross section of the wire in a day? Homework Equations i=n*A*v_d N_e=i*delta(t) The Attempt at a Solution First I …
Electron Drift Speed: Find Current Density & Current in a Gold Wire
2005年2月7日 · Since we know the electron drift speed in the gold wire is 3.0 * 10^-4, we can substitute this value for v in the formula I = nqva. We also know that the charge of an electron, q, is 1.6 * 10^-19 C, and the number of electrons per unit volume, n, for gold is 5.9 * 10^28 m^-3.
What are (a) the current density and (b) the electron drift speed?
2011年5月8日 · Meanwhile, the electron drift speed is influenced by the strength of the electric field, the type of material, and the temperature. How can the current density and electron drift speed be measured? The current density can be measured using a device called an ammeter, which measures the amount of current passing through a given area.
