Electrostatics
Electric Charge:
A fundamental intrinsic property of matter that gives rise to
the attractions and repulsions between electrons and protons.
Coulomb:
The typical unit for measuring charge; a set number of electrons. 1
Coulomb = 6.25x1018 electrons
Charging by Contact:
The transfer of electric charge from one object to another by simple
contact or conduction.
Charging by Induction:
Redistribution or charging of an object by bringing a charged item
in close proximity to, but not touching, an uncharged object.
Coulomb�s Law:
Mathematical relationship between electric force, charge, and
distance. The electric force varies directly with the product of
the charges, and inversedly to the square of the distance between
the charges.
Polarization:
Separation or alignment of the charges in a neutral body so that
like charges are grouped together, resulting in a positive and a
negative region.
Electric Field:
A force field that fills the space near any charge.
Electric Potential:
The ratio of electric potential energy to electric charge at a
particular spot in an electric field. It is often referred to as
voltage since it is measured in volts.
Equipotential Line:
A line where all points have an equal electric potential, or
voltage.
