Electric potential and electric field

Click For Summary

Discussion Overview

The discussion revolves around the relationship between electric potential and electric field, specifically addressing whether a constant electric potential implies a zero or non-zero electric field. The scope includes conceptual understanding and mathematical reasoning related to electrostatics.

Discussion Character

  • Conceptual clarification
  • Mathematical reasoning
  • Debate/contested

Main Points Raised

  • One participant questions whether the electric field is zero or non-zero in a region where the electric potential is constant.
  • Another participant prompts others to consider the relationship between potential and field, suggesting that understanding potential difference is crucial.
  • A participant proposes that the electric field would be zero, citing the equation E = delta V / delta d, where a constant potential implies delta V = 0.
  • Another participant encourages confidence in mathematical reasoning, suggesting that mathematical results are generally reliable.

Areas of Agreement / Disagreement

There is no consensus on whether a constant electric potential leads to a zero electric field, as participants express differing views and reasoning.

Contextual Notes

Participants reference mathematical relationships and concepts that may depend on specific definitions or assumptions about electric potential and field, which remain unresolved in the discussion.

The potential is constant throughout a given region of space.Is electrical field zero or non-zero?

Have you looked up the relationship between Potential and Field? What does it tell you? What does Potential Difference mean?
Would you need to do work (or get it out) to move a charge in the direction of a field? This is all good old book work and it would be better for you to look it up for yourself.
 
Tell us what you think, and why, and someone will be glad to correct you if necessary.

I think that it would be zero because E=delta V / delta d. As V is constant therefore delta V =0
 
You should have more confidence. Did it seem too good to be true? :)
There are not many occasions where the Maths gives you the wrong answer. (It's probably more reliable than some old loony, answering you on PF.)
