Electrons moving from the valence band of one atom to another is the basis for what we call the flow of an electrical current. Electrical current is the quantity of the electrons moving from atom to atom. This flow is measured as Amperes, or some variation of that. Voltage is the potential difference between to terminals of an energy source, such as a battery.

Hi Ahmed.
I could get all technical, but I shan't today.
As a power engineer, I visualise such things in hydraulic terms, or straightforward plumbing.
In that the voltage represents the pressure, or head of water, and the current is the volume of water flowing through a given pipe.
So the volume of water delivered at the output is equivelent to the power available.
Heck V=IR , and Watts = Volts * Amperes, at unity power factor.
Though I have yet to talk to a plumber or hydro-engineer dealing with power factors, although they do deal with -
Cable size refers to pipe diameter
Resistance relates to valves, taps, bends etc down the pipe.
Current is related to either a small dribble, or being knocked over by a water-cannon.
This minor philosophy is recipricated, in water folks understanding electic folks.
Cheers with either !
Bob

Current is the rate of flow of electric charge from one terminal to the other. And it is measured in Ampere .Whereas, Voltage is the Potential difference between the two terminals and it is measured in Volts.

It refers to a graph, where current is on the y axis and voltage is on the x axis.
It basically shows you how the current varies with the voltage.

Current is the rate at which electricity flows with time i.e how fast the vodka goes from your mouth to your belly.
Voltage is the potential difference between two points i.e Is the vodka strong enough to knock you out?

current is the size of the electricity, voltage is the push behind it.
