We learned already that the electric field is perpendicular to the surface of a conductor (otherwise charges would accelerate along the surface), and equipotential lines are always perpendicular to the electric field lines. Example: Let’s consider as an example 2 conducting spheres connected by a thin conducting wire.

Note that they went a little overboard and marked equipotential curves (the magenta circles) at V = 0.25 V, 0.5V and then from V = 1 V to V = 10 V in 1 V increments. They followed the convention that red was their positive electrode (V = +10 V) and blue was ground (V = 0 V). E01-5
