A measure of the quantity of electricity determined by the amount of an electric current and the time for which it flows. A measure of the quantity of electricity (determined by the amount of an electric current and the time for which it flows).
• CHARGE UNIT (noun). The noun CHARGE UNIT has 1 sense: 1. a measure of the quantity of electricity (determined by the amount of an electric current and the time for which it flows). Familiarity information: CHARGE UNIT used as a noun is very rare. stat·cou·lomb. The electrostatic unit of charge, such that two objects, each carrying such a charge and separated (center to center) by 1 cm in a vacuum, will repel each other with a force of 1 dyne (or 10 -5 newton); equal to 3.335641 × 10 -10 coulomb. Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. Part of the Electronics glossary: In physics, charge, also known as electric charge, electrical charge, or electrostatic charge and symbolized q, is a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons. The coulomb (symbolized C) is the standard unit of electric charge in the International System of Units (SI). It is a dimensionless quantity, sharing this aspect with the mole. A quantity of 1 C is equal to approximately 6.24 x 10 18, or 6.24 quintillion. Definition of COULOMB. : the practical meter-kilogram-second unit of electric charge equal to the quantity of electricity transferred by a current of one ampere in one second. See coulomb defined for kids. ADVERTISEMENT. Voltage is electric potential energy per unit charge, measured in joules per coulomb (= volts). Voltage. Voltage is electric potential energy per unit charge, measured in joules per coulomb (= volts). It is often referred to as electric potential, which then must be distinguished from electric potential energy by noting that the potential is a per-unit-charge quantity.
