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.
Voltage ( = Electric Potential ) An electric charge alters the space around it. Throughout the space around every charge is a vector thing called the electric field. Also filling the space around every charge is a scalar thing, called the voltage or the electric potential. Electric fields and voltages are two different ways to describe the same thing. (Note on terminology: The text book uses the term electric potential, but it is easy to confuse electric potential with potential energy, which is something different. So I will use the term voltage instead.) Voltage overview The voltage at a point in empty space is a number (not a vector) measured in units called volts (V) . Near a positive charge, the voltage is high. Far from a positive charge, the voltage is low. Voltage is a kind of electrical height. Voltage is to charge like height is to mass. It takes a lot
