In this way the equipotential lines can easily be picked out.
Let S represent the sun, and the circle round it represent the equipotential spheres which exist round the sun.
This only means that the equipotential surfaces are crowded together, just as they are near the ridge of a house.
This cambium, therefore, also deserves the name of an equipotential system.
Hence the distances separating the equipotential surfaces are a measure of the electromotive force present.
When the lines of force and the equipotential surfaces are straight, parallel, and equidistant, we have a uniform field.
The germs of certain medusae seem to be equipotential in every respect, even in their cleavage stages.
Each ring represents an equipotential line in the field of diffusion.
