Exam-style question
Try this first
Explain how electric potential is related to electric field strength.
Model answer
What a good answer should say
- Electric potential is related to electric field strength as the electric field strength is the negative gradient of the electric potential.
- This means that a change in electric potential over a distance gives the electric field strength.
Explanation
Why this works
This answer effectively connects electric potential and electric field strength, demonstrating an understanding of their relationship. The question assesses the ability to explain concepts in electric fields.
