A flow of electrical charges is the definition of an electric current. This is a far better definition than 'a flow of free electrons', which one normally hears, because a current can be a flow of free electrons, positive or negative ions, 'holes', etc. -depending on the medium through which the current is flowing.
Not really. You can compare them with the analogy of water flowing through a pipe. For water to flow, there must be a pressure difference across the ends of the pipe. An electric current is a movement of electric charges along a conductor. For those charges to move, there must be a voltage (more accurately, a 'potential difference') across the ends of the conductor. So a potential difference is required to cause current to flow.
It is measured in amps. It is related to voltage and resistance by Ohm's Law. It is the flow of electric charges.
Voltage causes current to flow in an electric circuit.
Electric currents flow from the source through the circuit and back to the source in materials called conductors.
A continuous flow of negative charges is called an electric current.
The flow of electric charges is current.
Charges flow through a conductor when there is a potential difference (voltage) present, causing electrons to move in the direction of the electric field. This flow of charged particles is what creates an electric current.
Electrons are a negative charge. Using conventional notation current flows from positive to negative poles of a battery, for example. In electron flow convention the electrons flow from negative to positive.
The flow of electric charges creates an electric current, which is the movement of electric charges through a conductor. This current can be harnessed to power electrical devices and systems.
It is called an electric current.

Yes because only electrons(negatively charged) can travel.
Conventional current flow is the idea that electric current flows from the positive terminal of a power source to the negative terminal. This concept is used in circuit analysis and is opposite to the actual flow of electrons, which move from the negative terminal to the positive terminal.
