Why ampere considered as a fundamental unit though it is a derived one?
Because you have to start somewhere - you can't derive ALL units. You have to have SOME fundamental units.For example, 1 ampere = 1 coulomb / second. That also means that 1 coulomb = 1 ampere x 1 second, or that 1 second = 1 coulomb / 1 ampere. In other words, you can derive any of the three units from the other two. In practice, for base units, units were chosen that can be measured with great precision.Another AnswerThe ampere is not a 'fundamental' unit; it is a base unit. The ampere was chosen as a base unit, because it relates electrical units to mechanical units, being defined, as it is, in terms of the force (which itself is defined in terms of base units) between current-carrying conductors.You might be getting confused because, quite wrongly, the ampere is often defined as a 'coulomb per second'. While it is certainly equivalent to a coulomb per second, it is not definedin this way.
What is the base unit of electric current in the International System of Units, commonly denoted as the ampere?
The base unit of electric current in the International System of Units is the ampere, commonly denoted as "A."
What units is equivalent to coulomb per second?
A coulomb per second is equivalent to an ampere, which is the unit for electric current.
What is the breakdown of the ohm units?
The ohm unit measures electrical resistance. It is represented by the symbol . The breakdown of the ohm unit is as follows: 1 ohm is equal to 1 volt per ampere. This means that if a voltage of 1 volt is applied across a circuit and it produces a current of 1 ampere, then the resistance of the circuit is 1 ohm.
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.
What are the units of measurement for current?
The standard unit is the ampere, commonly called "amp", symbol 'A'.

What are the units for an electrical current?
ampere
What is the standard unit of measurment in the international system of measurment?
The basic standard units are:kilogram (mass)meter (distance)second (time)ampere (electric current)kelvin temperature)mole (amount of chemical substance)candela (luminous intensity).
What are the units for mesuring current?
A - ampere is the SI unit for current. But practically we use milli ampere (mA), micro ampere (,u A)
What are the standard units of measurement in the metric system?
-- Kilogram = Mass -- Meter/Metre = Length -- Second = Time -- Ampere = Electric current -- Kelvin = Temperature -- Mole = Amount of substance -- Candela = Luminous intensity Are the above are known as base units. Other units are known as derived units
The units for current?
ampere (A) or milliamp (mA)
Are the coulomb and ampere both units of charge?
coulomb is the unit of charge and ampere is unit of current
What are the base units of charge?
The coulomb. It is the charge transported by 1 ampere of current in 1 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
What units is used for currents?
Ampere is the unit of current.
What are 2 units for measuring current?
The 2 units for measuring current are: Ampere Milliampere
