Oh Culomb, I know your law well,

using it, it is so simple to tell,

the force between two point charges, no matter how far,

is dependent on their charge and how far away they are.



Electric field can tell you how strong a force would be,

or give you information about energy density.

They aren't real, just a construct of the mind,

still it's hard to do physics without those imaginary lines.



Electric Potential Energy is easy to find,

if one will simply keep in mind,

the method to use, and apply some persistence,

take the integral of force with respect to distance.



Electric potential, or Voltage as some say,

is Electric Potential Energy, with charge taken away.

It's not a hard concept, but it involves some tricky math,

it is the integral of Electric field perpendicular along a path.
