Definition of "Coulomb" |
Coulomb (abbreviated C) is the standard measure of electrical charge. Named after Charles-Augustin de Coulomb, it is the amount of charge accumulated on a one-farad capacitor charged to one volt; or the amount of charge transported by a one ampere current in one second. / A measure of the quantity of electricity. One coulomb is equal to 6.28 x 1018 electrons. / SI unit of electric charge. One coulomb is equal to the amount of charge accumulated in one second by a current of one ampere. / The coulomb named after Charles-Augustin de Coulomb, unit symbol: C is a fundamental unit of electrical charge, and is also the SI derived unit of electric charge symbol: Q or q. It is equal to the charge of approximately 6.241×1018 electrons. / In telecommunication preemphasis is the intentional alteration of the amplitude-vs-frequency characteristics of the signal to reduce adverse effects of noise in a communication system. / unit of electric charge. A negative coulomb charge consists of 6.24 × 10^18 electrons. |
