equipontential

Definition

Adjective (Physics): - Having equal potential: "equipotential" describes a surface or line where every point has the same electric potential (voltage). In such a region, no work is required to move a charge along it.

Usage Examples

• (All points on the sphere have the same electric potential.)
• (Field lines cross equipotential lines at right angles.)

Advanced Usage

• "equipotential surface": a three-dimensional surface where the electric potential is constant.
  • Conductors in electrostatic equilibrium have an equipotential surface. (The entire conductor is at the same potential.)
• "equipotential line": a two-dimensional curve where the potential is constant, often used in field maps.
  • In a topographic map, contour lines are analogous to equipotential lines in electrostatics. (Contour lines show equal height, just as equipotential lines show equal voltage.)

Variants and Related Words

• Equipotentiality (noun): the state or property of being equipotential.
  • The equipotentiality of the metal sphere ensures no current flows inside. (The property of having equal potential everywhere.)

Synonyms

• Iso-potential: a term used less commonly, meaning the same as equipotential.
• Constant-potential: describing a region where potential does not vary.
