10 joules of work to move 5 coulombs 10 V/m electric field across a 2 meter plates 90 meters away from a 2nC charge
Potential, electric potential, and potential difference whose symbol is V refer to the amount of work energy needed to move a unit of electric charge a certain distance in an electric field. (This is not the same as electric potential energy whose symbol is U!!) Here are some different formulas for electric potential, V, in different problems: Work to move an amount of charge: V=w/q clipart 2 charges on x-axis-2.JPG Potential difference between two charged plates: V=Ed clip art electric field plate-2.jpg Electric potential at a distance from a charge: V=kq/r clipart 2 charges on x-axis-3.JPG What's the electric potential involved for each case below?
