What does the area under the curve in an electric potential graph represent?.
- A.Electric field strength
- B.Work done moving a charge
- C.Charge
- D.Potential energy
Model answer
What a good answer should say
- Work done moving a charge
Explanation
Why this works
The area under the curve in an electric potential graph represents the work done in moving a charge between two points in the electric field. This shows the relationship between potential difference and work, implying that a larger area indicates more work is required to move the charge.
Therefore, the conclusion is that the area under the curve signifies the work done moving a charge.
