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.
Units for electric potential and fields Previously, we noted that electric forces are in Newtons (N), electric potential energies are in Joules (J), and charge is measured in Coulombs (C). Since electric fields and potentials are obtained by dividing the force and potential energy, respectively, by the charge they are measured in units of (N/C) and (J/C) respectively. But a Joule per Coulomb is also known as a volt (V), and the electric potential can also be referred to as the voltage.
