Mean drift velocity
Explore mean drift velocity within charge and current. Electric current is a rate of flow of charge. Connect the macroscopic current to the motion and number of charge carriers in a conductor.
Specification outcomes (3)
- 4.1.2(a) Define and understand mean drift velocity of charge carriers.
- 4.1.2(b) Use and apply I = A n e v, where n is the number density of charge carriers.
- 4.1.2(c) Distinguish between conductors, semiconductors and insulators in terms of number density of charge carriers.
