What each symbol means
| Symbol | What it stands for |
|---|---|
| A | Cross-section (m²) |
| I | Current (A) |
| e | Elementary charge (C) |
| n | Free electron number density (m⁻³) |
| v_d | Drift speed magnitude (m/s) |
When to use this
Classical Drude picture; uniform current; scalar form for magnitude.
