Current is considered a base quantity because it is a fundamental physical quantity that cannot be defined in terms of other physical quantities. It describes the rate of flow of electric charge in a circuit and is measured in units of amperes (A). Charge, on the other hand, is a derived quantity that depends on current and time, making current the more fundamental quantity.

What physical quantity corresponds to the rate of flow of charge?
The physical quantity that corresponds to the rate of flow of charge is current, which is measured in amperes (A). Current represents the flow of electric charge per unit of time through a conductor.
Is current a vector or a scalar?
Definitely current is a SCALAR. Current density, of course, is a vector quantity Current = charge / time Both charge and time are scalars Current density = current / area Here area is a vector quantity Hence scalar product of current density and area give scalar quantity i.e. current. So electric current is a scalar Of course we assign +ve and -ve sign to currents. It is not because of direction as we do incase of vectors. But it is only algebraic sign.
Why current density is a vector quantity when current is scalar quantity?
Current density is a vector quantity because it has both magnitude and direction. It represents the flow of electric charge per unit area in a specific direction, as opposed to current which is the total amount of charge flowing through a conductor. The direction of current density indicates the direction in which the charges are moving.
Is electric current a derived or fundamental quantity?
Electric current is considered a fundamental quantity in physics. It is measured in units of amperes (A) and is one of the seven base SI units.
How is current fundamental physical quantity when current is equal to charge per unit time?
Current is a fundamental physical quantity that represents the flow of electric charge per unit time through a conductor. It is defined as the rate of flow of charge and is measured in units of amperes (A).
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.

Electric current is considered a fundamental quantity in physics. It is measured in units of amperes (A) and is one of the seven base SI units.
How is current fundamental physical quantity when current is equal to charge per unit time?
Current is a fundamental physical quantity that represents the flow of electric charge per unit time through a conductor. It is defined as the rate of flow of charge and is measured in units of amperes (A).
Why is charge not a fundamental quantity?
Because the measurement of current is more convenient.we may take direct reading of current.
Why is the electric current a base quantity?
Electric current is considered a base quantity because it is an independent physical quantity that cannot be defined in terms of other fundamental quantities. It is a fundamental building block in physics and is used to define other electrical quantities such as voltage and resistance.
Why electric current is base quantity not derive?
Electric current is considered a base quantity because it is an independent physical quantity that cannot be defined in terms of other physical quantities. Instead, other quantities like charge and time are defined in terms of electric current. This makes electric current a fundamental parameter in physics.
What is the difference between electric currents and electric charge?
Electric current is a flow of electrons is a measure of the quantity of electrical charge passing any point of the wire in a unit time.And, electric current is measured in ampere (A).Whereas, electric charge is the quantity of electricity that flows in electric currents . And , it is measured in coulomb (C)
Why electric current is not vector quantity?
Electric current is not a vector quantity because it does not have a specific direction associated with it. It is a scalar quantity that represents the flow of electric charge through a conductor. The direction of current flow is defined by the convention of positive charge flow from higher potential to lower potential.
What refers to the rate flow of electric charge?
The rate flow of electric charge is referred to as electric current. It is typically measured in amperes (A) and represents the quantity of charge passing through a conductor per unit of time.
