Electric Potential
Electric Potential & Electric Potential Energy
Imagine a universe that only consists of two protons, initiall at rest and very close to each other. We know what will happen, they will repel each other and accelerate away in opposite directions. In the initial state they had zero kinetic energy but that doesn't last. Where did that energy come from?
EP Field Patterns & Motion of Charges
Check out the equipotential surfaces of a bunch of charges dancing around each other.
Connecting Electric Potential & Electric Field
It is easy to measure the electric potential using a volt meter. If you can map out the voltage in some region of space, you can determine the electric field from that voltage map. It is in this way that once you know the electric potential, you know everything.
