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 ampere a unit of?
Ampere is the basic unit of electrical current.AnswerThere are, in fact, two answers. The ampere is the SI Base Unit for electric current, but it is also the SI Derived Unit for magnetomotive force.
What is the SI unit of charge?
coulomb ----------------------------------------- Coulomb (symbol C) is a derived unit for electrical charge in SI; the base units are: 1 C = A x s So, the coulomb is the electrical charge transported by an ampere in one second.
What is the base unit of voltage?
The base unit of voltage is the volt, a combined unit meaning joules per coulomb.AnswerThe SI unit for voltage is the volt (symbol: V), which is a derived unit -not a base unit. There are seven base units in the SI system: metre, kilogram, second, ampere, candela, kelvin, and mole. SI units which are not base units are termed 'derived units'.
What is the basic unit of charge?
The SI derived unit of electric charge is the coulomb(C).In electrical engineering, it is also common to use the ampere-hour (Ah).In chemistry and particle physics, it is common to use the elementary particle charge (e) as a unit.Independent of units, the symbol Q often denotes charge.
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
Is a ampere a derived unit?
No, the ampere is not a derived unit. It is a base SI unit that represents electrical current. It is defined as the amount of electric charge that flows through a conductor per unit time.
Is coulomb an S I base unit?
No, a coulomb is a derived unit. A base unit is a unit that isn't made by combining other units. There are seven base units, including metre (length), kilogram (mass), and second (time). Coulomb is the unit of electric charge. One coulomb is the charge delivered by a steady current one ampere in one second. It is derived from the base units ampere (electric current) and second (time).
What are the base units of charge?
The coulomb. It is the charge transported by 1 ampere of current in 1 second.
What are the unit of charge?
The SI unit of charge is the coulomb. In the SI, this is NOT a "base unit"; it's a derived unit - 1 coulomb = 1 ampere x 1 second.
What is the ampere a unit of?
Ampere is the basic unit of electrical current.AnswerThere are, in fact, two answers. The ampere is the SI Base Unit for electric current, but it is also the SI Derived Unit for magnetomotive force.
Is the ampere a unit of quantity or a unit of rate?
The ampereOnce upon a time, the coulomb was defined as the fundamental unit of charge, and the ampere was a derived unit proportional to charge (in coulombs) and inversely proportional to time (in seconds). More specifically, one ampere is equal to a charge transfer rate of one coulomb per second. So, it is a rate -- a charge-transfer rate. Nowadays, the ampere is considered the fundamental unit, and the coulomb is the derived unit. In other words, the coulomb is the amount of charge delivered in one second by a current of one ampere.AnswerThe coulomb has never ever been considered a Base Unit in either the SI or earlier metric systems. The ampere has always been considered a Base Unit. Prior to 1948, the ampere was defined in terms of its chemical effect; after 1948 it was defined in terms of its magnetic effect -i.e. in terms of the force between two, parallel, current-carrying conductors. So, the ampere has never been defined as an unit of rate. On the contrary, the coulomb is a Derived Unit, based on the ampere and the second.
What is the current flow of one coulomb per secound?
That is called an Ampere. By the way, in the SI the Ampere is defined as a base unit; the Coulomb is the derived unit.
Why ampear is a fundamental unit?
The ampere is a fundamental unit because it is a base unit in the International System of Units (SI) for measuring electric current. It is essential for quantifying the flow of electric charge in a circuit, making it fundamental in the study of electricity and magnetism.
What is the SI unit of charge?
coulomb ----------------------------------------- Coulomb (symbol C) is a derived unit for electrical charge in SI; the base units are: 1 C = A x s So, the coulomb is the electrical charge transported by an ampere in one second.
What is the measure of 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.
What is the base unit of electric current flow?
The base unit of electric current flow is the Ampere, symbolized as A. It is defined as the flow of one Coulomb of charge per second.
Why current a fundamental quantity though it is flow of charge per unit time?
Ampere = Coloumb / second is the same as saying that Coloumb = Ampere x second. Any of the two electrical units can be derived from the other one. Ampere is NOT a "fundamental quantity"; it is an SI base unit. The base units are not necessarily those that are somehow considered more "fundamental" than others; instead, the base units are those that can be measured with a great accuracy. In the case of current vs. charge, it seems that measuring a current can be done with greater accuracy than measuring a charge directly; therefore, the current is the base unit, and the current is derived. However, this doesn't make current any more "fundamental" than charge.
