Drift Velocity Flashcards
1
Q
What is the equation for drift velocity?
A
Drift Velocity (v) = Length of wire/time
Or
Current = Electron Density x cross sectional area x drift velocity x the charge of an electron (I = NAve)
2
Q
What is the equation for electron density?
A
Electron density (N) = number of electrons/ volume
3
Q
For an electron density of 1x1029, a current of 1 and cross sectional area of 2.7x10-6, find the drift velocity (v)
A
2.31x10*-5m/s or 23.1µm/s
