1
New cards

  • define mean drift velocity

  • the net velocity of electrons travelling through a conductor

2
New cards

  • state the formula for electric current including mean drift velocity

  • I = Anev

    • electric current (A) = cross-sectional area of the conductor (m²) × number density (m-3) × elementary charge × velocity (ms-1)

3
New cards

  • state the relationship between cross-sectional area and mean drift velocity

  • inversely proportional

4
