A difference in charge
A potential difference, or voltage, is necessary for a sustained flow of electric charge through a conducting medium. This potential difference creates an electric field that pushes the charges through the conductor. Without a potential difference, the charges will not move and no current will flow.
A potential difference (voltage) across the conducting medium is necessary for a sustained flow of electric charge. This potential difference creates an electric field that pushes the charges through the conductor. Without a potential difference, there would be no force to maintain the flow of charges.
The necessary condition for a charge to move in a wire is the presence of an electric field, which exerts a force on the charge causing it to move. This movement of charges in a wire is what constitutes an electric current.
The necessary condition for the sustained flow of charge in a wire is the presence of a closed circuit or path for the current to flow in. This closed path allows the charges to continuously move and circulate through the wire. Additionally, an external source of electromotive force, such as a battery or a power supply, is required to provide the energy needed to maintain the flow of charge.
True. Electric current is the flow of electric charge through a medium. It is typically measured in amperes (A) and represents the rate of flow of electric charge.
By the application of a voltage source electric charge will flow.
In order for charge to flow, there must be a potential difference present across a conductor. This difference in electric potential creates an electric field that drives the movement of charge through the material.

For the sustained flow of water in a pipe, there must be a continuous pressure difference driving the water from a high-pressure area to a low-pressure area. Similarly, for sustained flow of electric charge in a wire, there must be a continuous voltage difference (or electric potential difference) between two points in the circuit, which drives the flow of electrons from the negative terminal to the positive terminal. Both scenarios rely on a gradient—pressure for water and voltage for electric charge—to maintain flow.
Electric Current is the flow of electrons and hence charge

Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
The flow of electric charge through a conductor is called electric current.
