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)

What condition is necessary for electric charge to flow?
For electric charge to flow, there must be a potential difference (voltage) between two points in a conducting material. This difference in potential creates an electric field that exerts a force on the charges, causing them to move. Without a potential difference, charges will not flow.
What is the definition of potential defference?
Potential difference is the difference in electric potential between two points in an electric field. It is measured in volts and represents the work done per unit charge in moving a test charge between the two points.
What Electric potential or potential difference?
Electric potential (also known as voltage) is the amount of electric potential energy per unit of charge at a specific point in an electric field. It is measured in volts (V) and determines the ability of a charge to do work. Potential difference is the difference in electric potential between two points in an electric field and is responsible for the flow of electric current between those points.
What constitutes an electric current in a wire?
An electric current in a wire is the flow of electric charge, typically carried by electrons, through the wire. This flow of charge is driven by a voltage difference, or potential difference, between two points in the wire.
What is the difference between the movement of electric charge in a solution and the transfer of electric charge between solid objects?
In a solution, electric charge moves through the movement of charged particles (ions) in the liquid. In the transfer of electric charge between solid objects, charge is transferred through the movement of electrons between the objects. The mechanism of charge transfer and conduction is different in each case due to the nature of the medium involved.
What is the difference between electric charge and ion?
An electric current goes through an electric circuit, if it is closed.
What is the unit that measures electric currents?
The unit that measures electric currents is the ampere (A). One ampere is equivalent to the flow of one coulomb of charge per second.
The flow of electrons through a conductor is called?
The flow of electrons through a conductor is called an electric current. It is the movement of electric charge across a medium, typically driven by a voltage difference. Electric currents are fundamental to the operation of electrical devices and systems.
When a charge is flowing through a wire you have an electric?
When a charge is flowing through a wire, it creates an electric current. The flow of charges generates a magnetic field around the wire, as described by Ampere's law. This relationship between electric currents and magnetic fields forms the basis of electromagnetism.
What is true electric currents?
True electric currents refer to the movement of electric charge carriers through a conductor, such as electrons in a wire. It is this flow of charge that powers electrical devices and circuits. The direction of the current is defined as the flow of positive charge, even though in reality it is often negative charges (electrons) that are moving.
What is the transfer of electric charge between two objects that are touching one another?
The transfer of electric charge between two objects that are touching each other is known as conduction. This occurs when electrons move from one object to another due to the difference in electric potential between the objects.
How much electric charge does an object have?
An object's electric charge is typically measured in coulombs (C). The electric charge of an object depends on the number of protons and electrons it contains. Protons carry a positive charge, while electrons carry a negative charge. The total charge of an object is the difference between the number of protons and electrons.
