Takoma Park. Add to Calendar 2015-05-02T04:00:00 35 Free Comic Book Day Come celebrate Free Comic Book Day; a national event to promote reading for all ages. As long as supplies last on May 2, weâll be giving away various comics donated by multiple comic book distributors. Comics will be available until the library closes or we run out of books to give away.
electric potential, potential, potential difference, potential drop, voltage(noun) the difference in electrical charge between two points in a circuit expressed in volts. electric potential(Noun) the potential energy per unit charge at a point in a static electric field; voltage. Electric potential. In classical electromagnetism, the electric potential at a point is the amount of electric potential energy that a unitary point charge would have when located at that point.
Electric potential is actually defined as the NEGATIVE potential function of electric field (not the vector calculus potential function, but its negative), as is any concept of potential in physics, in order that we can think of it as a form of energy. This means that electric field is the negative gradient of electric potential. If you've never heard of the term gradient, all it means is a vector of derivatives of a scalar function of space, each component of which is a derivative of this function relative to the respective direction in the coordinate system.
