Drift speed

  • #1
The drift speed of the electrons in a copper wire running from a battery to a light bulb and back is approximately 0.020 mm/s. The battery is at the front of the classroom and wire runs out of a perimeter of the room to the light bulb. The total length of wire is 40meters. How long would it take a single electron to drift from the negative terminal of the battery and back to the positive terminal? Express your answers in days as well.

Do you know the equation that relates distance travelled, time and speed?
