In electrostatics, the coefficients of potential determine the relationship between the charge and electrostatic potential (electrical potential), which is purely geometric:
where Qi is the surface charge on conductor i. The coefficients of potential are the coefficients pij. φi should be correctly read as the potential due to charge 1, and hence "" is the p due to charge 2 on charge 1.
or more formally
Note that:
- pij = pji, by symmetry, and
- pij is not dependent on the charge,
The physical content of the symmetry is as follows:
- if a charge Q on conductor j brings conductor i to a potential φ, then the same charge placed on i would bring j to the same potential φ.
In general, the coefficients is used when describing system of conductors, such as in the capacitor.

Famous quotes containing the word potential:
“A child is born with the potential ability to learn Chinese or Swahili, play a kazoo, climb a tree, make a strudel or a birdhouse, take pleasure in finding the coordinates of a star. Genetic inheritance determines a childs abilities and weaknesses. But those who raise a child call forth from that matrix the traits and talents they consider important.”
—Emilie Buchwald (20th century)
