I think this picture represents the voltage because its the amount of energy requierd to move a charge, this charge is mesured in volts. The voltage is the work done to move the charge between two points, in an specific circuit, is electric potential energy per unit charge, we measured with a voltmeter.
What is potential energy? Potential energy is energy that is stored and can be turned into kinetic energy, the energy of motion. A ball held at some height above the ground has potential energy caused by gravity; when the ball is dropped, it falls at an increasing rate, increasing its kinetic energy while decreasing its potential energy. The potential energy is converted to kinetic energy during the fall. On the other hand, a ball resting on the level ground has no gravitational potential energy; it has no potential for movement unless acted on by an outside force (other than gravity). Potential energy can come from gravity, but also from elasticity, such as a rubber band. When a rubber band is stretched, its potential energy increases; when it is released, it snaps back (kinetic energy), and its potential energy returns to zero. Engineers must understand both potential and kinetic energy. A simple example is the design of a roller coaster—a project that involves both mechanical and civil engineers. When the roller coaster reaches the highest point (before the biggest drop), the cars must have enough potential energy to power them for the rest of the ride. This is done by raising the cars to a great height, increasing their gravitational potential energy. Then, the potential energy of the cars is converted into enough kinetic energy to keep them in motion for the length of the track.
