• How can I calculate the wave propagation speed in a copper ...

    To calculate the propagation speed, you need to specify the return current path in addition to the "forward" path. The reason is that the electromagnetic fields that determine the propagation characteristics fill the space between the two conductors. [If you try to calculate the inductance of a single wire, you get an infinite result.]

  • How fast do electrons travel when moving as an electrical ...

    Thus, the actual drift speed of these electrons through the conductor is very small in the direction of current. For example, the drift speed through a copper wire of crosssectional area x 10 6 m 2, with a current of 10 A will be approximately x 10 4 m/s or about a quarter of a milimeter per second.

  • Ohm's Law, Microscopic View

    The Fermi energy for copper is about 7 eV, so the Fermi speed is. The measured conductivity of copper at 20°C is. The mean free path of an electron in copper under these conditions can be calculated from. The drift speed depends upon the electric field applied. For example, a copper wire of diameter 1mm and length 1 meter which has one volt ...

  • Distance Makes a Difference: Fiber Optics or Copper?

    May 18, 2015 · Because fiber transmits data as a series of light pulses instead of electrical current, it can carry much more data, and the data can be carried further. There are many advantages in using fiber optic cable over copper, including costs as well as fiber's immunity to EMI and RFI, which means very little signal loss so data travels further, faster.
