Question

What is an equipotential line? What is an equipotential surface?

a) Lines of constant charge density; a surface with no charge.

b) Lines of constant potential; a surface with constant electric field.

c) Lines of constant electric field; a surface with constant potential.

d) Lines of constant voltage; a surface with no electric field.

Answer 1

An equipotential line is a line along which the electric potential is constant. An equipotential surface is a three-dimensional version of equipotential lines. They indicate regions where the electric potential is the same.

Step-by-step explanation:

An equipotential line is a line along which the electric potential is constant. An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines. They indicate regions where the electric potential is the same.
