What Equipotential Means
Equi same Potential potential
equipotential lines lines where the potential is the same.
If you follow field lines, the electric potential decreases.
Electric Field lines are always perpendicular to the equipotential lines.
The closer the equipotential surfaces, the stronger the fields.
Drawing Equipotential Lines
For a Single Charge

What would the electric potential between them be?
Equipotential In Uniform Fields
Let’s draw the equipotential lines between two parallel plates.

*1986E1. Three point charges produce the electric equipotential lines shown on the diagram above.
a. Draw arrows at points L, N. and U on the diagram to indicate the direction of the electric field at these
points.
