noun ,Physics. one of the basic properties of the elementary particles of matter giving rise to all electric and magnetic forces and interactions. The two kinds of charge are given negative and positive algebraic signs: measured in coulombs....
q1 and q2 = the charge of each particle in Coulombs (C) r = distance (m)The bigger either of the charges the more force there is, but the force decreases by the square of the distance.Example: Two electrons 1 mm Apart The charge of a single electron is only about −1.6 x 10-...

Charge is a fundamental measurement in physics, much as length, time, and mass are fundamental measurements. The fundamental unit of charge is theCoulomb[C], which is a very large amount of charge. Compare that to the magnitude of charge on a single proton or electron, known as anelementary...
Electric charge Electric charge, also referred to simply as charge, is a basic property of some fundamental particles of matter. There are two types of charge: positive and negative. For example, an electron has a negative charge, and a positron (an anti-particle of electron) has a positive...
All charges in nature exist as integral multiples of electron charge, i.e., q = n.e. A coulomb is equivalent to a charge of 6.2431018electrons. When a body is positively charged, its mass slightly decreases. When a body is negatively charged, its mass slightly increases. ...
A statcoulomb is defined as 10c coulomb where c is the magnitude of the speed of light, and is energy-equivalent to the unit square root cubic centimeter square root gram per second (cm32/g√s). An electron is the electric charge on an electron, or approximately 1.60217733×10−19 coul...
Charge is a property of a particle and can be positive or negative. For example, an electron has a charge of negative 1.6 x 10^-19 coulombs. Coulomb is the unit of charge. Charges create electric fields, and the electric field created by one charge will cause other charges nearby to ...

-drop experiments. By comparing applied electric force with changes in the motion of the oil drops, he was able to determine the electric charge on each drop. He found that all of the drops had charges that were simple multiples of a single number, the fundamental charge of the electron....
