In electric circuit we are interest in a flow of a current. Just like a water flow in pipe the current flow in the wire.
The force that cause the current to flow is a voltage or pressure in water analogy.
Voltage is "electrical pressure", current is a flow of a charge. So voltage is needed to move the charge (current to flow).
Voltage is present at a point or between two points, but voltage do not flow or move as current does.
For example if we have at one end of a wire 300 electron is missing and on the other end of a wire 500 electrons are missing.
Then we have the voltage between the two points.
Both these "points" are positive, but the first point (300 electrons missing) is negative with respect to the second point (500 missing electrons).
And if we connect these points with a conductive wire then current is star to flow. From more negative point to more positive point. And current will flow until the number of electrons on both ends will be equal (no voltage).
And in electronics circuit we don't use these V=W/q formula.
But Votages has something to do with work.
When two similarly charged particles are brought near, they try to repel each other while dissimilar charges attract each other.
This mean every charged particles has ability to do the work (to move charges) . So this ability of a charged particle to do the work is called electric potential.
