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.
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.
when a negative and a positive charges attract. or when there is a closed circuit.
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.
Current means flow. Electric current means flow of electric charges Now there are two kind of charges. They are positive and negative But current is defined as the flow of positive charges But in metallic wires there is no chance for positive charges to flow through. Only loosely bound electrons with negative charge are capable of flowing. So current is case of metallic wire is due to electrons. So we have to assign as "conventional current". Conventional current is always opposite to the flow of electron flow Now from a battery current (conventional) flows right from positive polarity to the negative polarity. But within batter is has to flow right from negative to positive so as to complete the circuit of flow.
It is called an electric current.

Yes because only electrons(negatively charged) can travel.

Electrons do not flow, but they might be though of as 'flowing' as they transfer charges between them. The reason that electron flow is the opposite direction from current is that historical theories of electrical flow (current) treated it as a movement of positive charges rather than negative charges.There is no actual difference that could be discerned, except that we now know that negative charges (electrons) constitute the basis of most common electricity.
Yes, an electric current is the flow of charged particles.
