Electric field and potential

  • #1
I understand that if electric field at any point is 0, it implies that potential is constant not necessarily 0. But what if the potential at a point is 0? Does it imply that electric field is 0? Me and my friend had an argument and I am in the favour of electric field not being 0. Do I win guys? Plz tell me I do

If the lectric field is zero at a point, then we know the gradient of the potential is null at that point.
If the potential is zero at a point, and this is the only information we have, we know nothing about the electric field

Potential is always relative to some other point. It's conventionally taken as referenced to 'Infinity'. It may be best to talk in terms of Potential Difference in this question.
