current is the flow of mobile electrons along a conductor and the process of transmission of these mobile electrons along the conductor is called electricity.

Current is the flow (movement) of electric charge. The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second.
Electricity is a general term for a variety of phenomena resulting from the presence and flow of charge.

Electricity is the phenomenon of the transfer of electrical energy.
This transfer of electrical energy is effected by the movement of electrons, or actually, the movement of positive charge along an electric conductor.
The amount of charge (Q) that traverses a cross sectional area (A) over a certain time (t) is the quantity known as current (I).
Therefore current is a quantity that tells us the amount of electrical energy that is being transferred from one point to another.

current is the rate at which electrical charges flow. electricity is kind of just a general term for electrical charges.

Electricity is the flow of electrical energy, it require three units, volts, resistance and current. Volt is a unit of pressure, resistance is measured in Ohms and current is measured in amperes.

current is the flow of electrons, electricity is more generally used for anything dealing with the presence and flow of charge :)

Current is usually measured in "Coulombs" per second, flowing past a point or through a plane.
Wikipedia says a coulomb is
6.241506×10^18 electrons

This was done by Volta.He made a pile of Copper and Zinc plates with a wet cloth of salt solution.Between them. Ivan
