A coulomb is a measure of electrical charge, specifically that one coulomb is approximately 6.24 x 1018 protons or (negatively) electrons.
An ampere, on the other hand, is a measure of electrical flow, in coulombs per second.
CommentThe ampere is actually defined in terms of the newton and the metre, not the coulomb and the second.
A coulomb is a measure of electrical charge. An ampere is a measure of electrical current flow, in coulombs per second.
Not asked, but answer for completeness sake; a volt is a measure of electrical potential difference in joules per coulomb, and a watt is a measure of electrical power transfer in joules per second.
Current is rate of flow of charge, so 1 ampere = 1 coulomb per second. As ampere and seconds are both fundamental units (and coulomb is derived), a coulomb has the dimensions [current][time] i.e. As
That's the coulomb, equal to the quantity of charge moved by a current of 1 ampere during an interval of 1 second.
In SI, the coulomb is a special name given to an ampere second, in much the same way that a watt is a special name for a joule per second.
an electrical charge is measured in Coulombs, which is equal one ampere-second. That is, one ampere of current through a plane is equivalent to one coulomb of charge passing through the plane per second.Current
A Coulomb is the unit of charge. It is a fundamental unit, representing the number of elementary charges (typically, electrons) available to do work. Its numerical value is about 6.241510x1018 elementary charges Important combined units based on the coulomb are the ampere, which is coulombs per second, the volt, which is joules per coulomb, and the volt-ampere, which is joules per second, or watts.
Electric charge / current.
A coulomb is a measure of electric charge. An ampere is a measure of electric current - how much charge passes per second. 1 ampere = 1 coulomb / second.
A coulomb is a unit for measurement of electrical charge and an ampere is the unit used for measurement of electric current.
Yes. The Coulomb is the SI unit of electric charge, and it is defined as the charge carried by a current of 1 amp in 1 second. Another way to look at this might be that the coulomb is a measure of charge (electrons) and the ampere is a measure of the rate of transfer of those charges.
The coulomb is a measure of electric charge, while an ampere (or amp) is a measure of current flow. These are SI units, and links can be found below to check facts and learn more.
Is a coulomb a measure of quantity whereas an ampere is a measure of rate?AnswerThe coulomb is the SI derived unit for electric charge. The ampere is the SI base unit for electric current.The coulomb is defined in terms of the ampere and the second. The ampere is defined in terms of the newton and the metre.
1 ampere = 1 coulomb/second 1 coulomb = 1 ampere x second
One ampere is equivalent to one coulomb per second.
"Amp" is a contraction for ampere. It is a unit of measurement for the flow of electrical current. 1 Ampere equals 1 Coulomb of electrons flowing past a point in 1 sec. Mathematically: 1 Amp = 1 C /sec For more discussion of a Coulomb see: http://en.wikipedia.org/wiki/Coulomb
The coulomb is an SI derived unit used to measure electric charge. It is a special name given to an 'ampere second', which are both SI base units.
coulomb is the unit of charge and ampere is unit of current
Although an ampere is equivalent to a coulomb per second, the ampere isn't defined in terms of a coulomb and a secondIn fact, the ampere has never been defined as a 'coulomb per second'. Think about it! An ampere is an SI Base Unit whereas the coulomb is a Derived Unit. So the coulomb must be defined in terms of an ampere, not the other way around!In fact, it is the coulomb that is defined in terms of the ampere and the second.Until the adoption of the mksA (metre, kilogram, second, ampere) system, the ampere was defined in terms of the mass of silver deposited, by electrolysis, over a specified period. With the adoption of the mksA (and, subsequently, the SI system), the ampere has since been defined as follows:'the constant current that, if maintained in two straight parallel conductors of infinite length and negligible cross-sectional area and placed one metre apart in a vacuum, would produce between them a force equal to 2 × 10-7newtons per unit length'.
