Drift velocity
v_d = eEτ/m
Where: E = energy (J) / electric field (N/C), e = electron charge (C) / coefficient of restitution, m = mass (kg), τ = torque (N·m), v_d = Drift velocity
Solved example
Given: E = 7, e = 5, m = 10, tau = 4
Find: v_d (Drift velocity)
- Formula: v_d = E·e·τ/m
- Substitute the values: v_d = 4·5·7/10
- Result: v_d = 14
Answer: v_d = 14
