Question

Explain in a sentence or two how can you map the equipotential lines.

Answer 1

Explanation:

Measure the equipotential lines for different two-dimensional configurations of conductors. 1. a) Draw equipotential lines near the positive and negative charges below with dashed lines. Draw solid electric field lines based on the fact that they are perpendicular to the equipotential lines at every point.

The equipotential lines can be drawn by making them perpendicular to the electric field lines, if those are known. Note that the potential is greatest (most positive) near the positive charge and least (most negative) near the negative charge.
