Ampere is a fundamental unit because it represents the base unit of electrical current in the International System of Units (SI). Electrical current is a fundamental physical quantity that plays a crucial role in many aspects of physics and engineering, making the ampere a fundamental unit of measurement.

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.
Why Ampere is a fundamental unit why?
Ampere is a fundamental unit because it is a base unit in the International System of Units (SI) and is used to measure electric current. It is defined in terms of the force between two parallel conductors carrying current, making it a fundamental aspect of electromagnetism and essential for understanding electricity in physics and engineering.
What Fundamental quantities of ampere?
The fundamental quantity associated with ampere is electric current, which represents the flow of electric charge over time. It is a fundamental unit of measurement in the International System of Units (SI) and is used to quantify the rate of flow of electric charge in a circuit.
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 fundamental quantities constitute 1 ampere of electric current?
The ampere is an SI base unit and is not defined in terms of charge and time at the moment. There is a proposal that has been put forward (2005), though still not ratified (2014) that would indeed define an ampere in terms of charge and time. Since the second is a fundamental unit and an electron a fundamental particle it is proposed to define an ampere as the rate of flow of fundamental charges. It is equivalent to 1 coulomb of charge flowing for 1 second. At the moment , the amp(ere) in fact, is defined in terms of the force between parallel, current-carrying, conductors. However, there is uncertainty in this measurement of a few parts in 10,000,000. So, if you were to break down the ampere, you would find it currently is defined in terms of the metre (a base unit) and the newton (a derived unit) which, in turn, is defined in terms of the base units kilogram, metre, and second.

Why we use force in defining ampere though ampere is a fundamental quantity?
Mass is a fundamental unit. Force is fundamental. Do you see a problem with this: Force = mass * accelation, or Mass = Force / acceleration Fundamental quantities are related to each other. There is no contradition to write an equation relating them to one another. An ampere can be defined as 1A = 1C/second.

What is the unit for measuring current?
The unit for measuring current is the ampere, symbolized as A.
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.
