What Equipotential surfaces and field lines means in Physics A-Level, as defined for AQA.
Definition of Equipotential surfaces and field lines
Check what you remember
Read the wording for your board, then hide it and explain Equipotential surfaces and field lines in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Surfaces on which potential is constant are always perpendicular to electric field lines; in a uniform field they are parallel planes and around a point charge they are concentric spheres.
