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.

What is dimensions of coulomb?
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
Why ampere is base unit if it is derived from charge?
The ampere is the SI Base Unit or electric current. It is NOT derived from the charge (coulomb) but from the force resulting from its magnetic effect. The ampere is defined in terms of the force between two, parallel, current-carrying conductors due to the interaction of their magnetic fields. The coulomb, on the other hand, is an SI Derived Unit, based on the ampere and the second.
What is the SI unit of electric charge?
That's the coulomb, equal to the quantity of charge moved by a current of 1 ampere during an interval of 1 second.
A coulomb is a measure of whereas an ampere is measure of?
Coulomb is a measure of electric charge:One coulomb is the amount of electric charge transported in one second by a steady current of one ampere.http://en.wikipedia.org/wiki/Coulomb
What is the value of one ampere?
The ampere is defined in terms of the force between two, parallel, current-carrying conductors.A current of one ampere flowing for one second will transport a charge of one coulomb. So a coulomb is an ampere second. Transposing this confirms that an ampere is equivalent to (not 'defined' as) a coulomb per second.
Can you give the meaning of coulomb in terms of ampere?
1 ampere = 1 coulomb/second 1 coulomb = 1 ampere x second
What is the ampere in terms of coulomb?
As an ampere is an SI base unit, it is NOT defined in terms of the coulomb. In fact, it is defined in terms of the force (in newtons) between two, parallel, current-carrying conductors. The coulomb, being an SI derived unit, is equivalent to an ampere second.
How is a coulomb used to define 1 amp?
1 coulomb per second = 1 amp.Note "coulomb" is the NUMBER of electrons....... "amps" is a measure of flow.AnswerAn ampere (not 'amp') is not defined in terms of coulombs, but in terms of the force between two, parallel, current-carrying conductors due to the interaction of their magnetic fields. However, an ampere is equivalent to (but not defined as) a coulomb per second.
How much is an amp in terms of charges flowing per second?
1 ampere = 1 coulomb / second. Actually, in the SI, it is defined the other way round; the ampere is the base unit, and the coulomb is defined as 1 ampere-second. However, it is easier to think of the ampere as 1 coulomb/second.
What is ampere in terms of coulomb?
1 Ampère = 1 Coloumb / second.
Give you the proper reason for one ampere equals one coulomb per second?
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'.
Define the ampere in terms of charge flow rate?
Although an ampere corresponds to a coulomb per second, this is not the way in which it is defined. Instead, it is defined in terms of the force between two, parallel, conductors, as follows:The ampere is defined as '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 × 10-7 newtons per unit length'.The importance of this definition is the fact that it provides a connection between mechanical and electrical units of measurement.The reason that an ampere cannot be defined in terms of a coulomb is that the ampere is a Base Unit, whereas a coulomb is a Derived Unit which, itself, is defined in terms of an ampere and a second.
How many coulomb one ampere?
One ampere = one coulomb every second .
What unit is represented for coulomb per second?
The ampere is one of seven SI base units, and is defined in terms of the force it produces between two, parallel, current-carrying conductors. It is incorrect to say that an ampere is 'defined' as a coulomb per second, although it is certainly 'equivalent' to a coulomb per second.The coulomb is a SI derived unit, and is defined in terms of the ampere and the second. In fact, it is a special name given to an ampere second.
Why ampear is a fundamental unit?
The ampere is not fundamental, it is derived from the coulomb and the second: ampere = coulomb / second
Are the coulomb and ampere both units of charge?
coulomb is the unit of charge and ampere is unit of current
What is a Ampere circuit?
The ampere (it is not capitalised), symbol A, is the SI Base Unit for electric current, which is defined in terms of the force between two, parallel, current-carrying conductors, due to the interaction of their magnetic fields, i.e: 'that constant current which, 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 × 10-7 newtons per unit length'.Note that the ampere is NOT defined in terms of the coulomb, as incorrectly stated in many references, because the coulomb itself (an SI Derived Unit) is defined in terms of the ampere -and you cannot define an ampere in terms of something that is already defined in terms of the ampere!!
