flow of charge is called current.
but the direction of flow of current is always taken oppsite to the flow of charge.
Voltage in an electrical circuit is the rough equivalent of pressure in a water pipe. It causes the electricity to flow. Higher voltage; more flow. The difference is that you can think of pressure applied at a single point, but voltage is always the difference in electrical potential between two points. That's how a bird can stand on a 7,000-volt rural electrical line without harm. The potential difference (voltage) between the line and the ground is 7,000 volts, but the potential difference (voltage) between the bird's two feet is very tiny.
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
there is a difference in electrical potential energy.
Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.
The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used. As an example: voltage is a difference in potental and is often considered the amount of pressure pushing an electrical charge or certain number of electrons through a conductor. This electrical charge is called current. Any conductor has resistance to the flow of charge or current. If for example a conductor has a resistance of 2 ohms and a voltage of 12 volts is applied the resulting current flowing in the circuit can be measured to be 6 ampere..the unit for current. Current is therefore, considered the intensity or amount of charge.Electricity then is the movement of this current of charge The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used.

When a voltage difference causes charge to flow from one point to another, it creates an electric current. This flow of charge can power electrical devices and circuits, allowing them to function.
The difference in electrical charge from one point to another measured in millivolts is called voltage. Voltage is a measure of the electrical potential difference between two points in a circuit and is responsible for the flow of electric current.
Actually, they need a difference in energy per charge. Voltage is energy per charge, in joules per coulomb, and a voltage differential is what is required to create an electric current 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.
Electronic charges will flow when a potential difference between the two locations, and an adequate path between them exists (with a low enough dielectric constant to allow the flow of charge - such as a wire). Electrons will move from here to there because there are "extra" electrons here, and there's some "missing" electrons there. Electrons have a specific charge. If you have "extra" electrons at one location relative to "missing" electrons at another location, you will have a negative voltage here, and a positive voltage (relative to here) there. This is called a potential difference (or voltage difference).
The pushing force that moves through a circuit is called voltage. It is the potential difference between two points in the circuit that causes the charge to flow.
Voltage is created in an electrical circuit through the movement of electrons from a higher potential to a lower potential, which generates a difference in electrical charge. This difference in charge, known as voltage, creates the force that drives the flow of electricity through the circuit.
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.
In order for charge to flow, a potential difference (voltage) needs to be present across a conductor. This voltage provides the electromotive force required to push the charged particles (usually electrons) through the material. Additionally, the conductor must provide a pathway for the charge to move, typically in the form of a closed circuit.

By the application of a voltage source electric charge will flow.
