W = qΔV
What each symbol means
| Symbol | What it stands for |
|---|---|
| W | Work done by electric field (J) |
| q | Charge being moved (C) |
| V_A | Potential at starting point A (V) |
| V_B | Potential at ending point B (V) |
| ΔV | Potential difference V_A − V_B (V) |
When to use this
Work by electric field moving charge from A to B. Path-independent (conservative field). W > 0 when +q moves from higher to lower potential.
