TermDefinition
Electric Field Lines Lines that indicate the path that a charged particle moves in when it is placed in an electric field.
Electric Potential The electric potential at any point in an electric field is the work required to bring one coulomb of positive charge from infinity to that point: V = W/q.
Electric Charge The positive or negative charge on an object
Induction The process of redistributing charges on another body by attracting or repelling electrons.
Conservation Of Charge If several conductors meet at a junction point, the algebraic sum of all the currents entering is equal to the sum of the currents leaving the junction (Kirchoff’s Law).
Electron A small, negatively charged particle found outside the nucleus of an atom.
Volt (V) The SI unit of electric potential or potential difference.
Static Electricity Refers to electrical charges at rest; that is, when the net flow of charge in any given direction is zero.
Elementary Charge Any charge is made up of integral multiples of a minimum charge called the elementary charge.
Static Charge The “electrical” charge on an object due to the loss or gain of electrons.
Electroscope A simple device in which a metal electrode is attached to two hanging pieces of metal foil and placed inside a glass container with the top of the electrode exposed at the top of the container.
Coulomb (C) The SI unit of charge, approximately 6.3 × 1018 elementary charges (from the List of Physical Constants in the reference information).
Grounding The addition or removal of electrons to or from an object in order to neutralize its charge.
Net Charge The algebraic sum of the positive and negative charges in a system.
Electric Field An electric field is said to exist in any region of space in which an electric force acts on a charge.
Electric Charge The positive or negative charge on an object
Electron A small, negatively charged particle found outside the nucleus of an atom.
Coulomb's Law The electrical force between two point charges is directly proportional to the product of the charges, and inversely proportional to the square of the distance between them.
